My theory: Haruto is a good ghost and there is a bad ghost disturbing Jae, so Haruto is giving Jae a special type of tea every night so he won't be disturbed by the bad ghost. What are your thoughts?

No wonder Haruto isn't afraid when they watch a ghost movie, that's his friend, Haruto is a good ghost

haruto is a good ghost, he doesn't even have any intention of hurting his friend

I swear Doyoung and Junghwan are so good, they have great acting potential and hopefully YG sees it and maximize it in the future.

Thanks for this DRAMA that made me get to know this wonderful band + who is your bias?

Haruto's facial expression is no joke. His eyes express so much emotions

*Theory:* Haruto is a good ghost, he's like Casper (the friendly ghost) since he was helping all of his friends. First, he helps Hyunsuk to make the bunshinsaba feels real by actually making the pen moves. Second, he knows that Junghwan wish to have a lot of subscriber so help him by showing his true form. Third, Jaehyuk was having a nightmare every night so he helps him by giving him chrysanthemum tea so he could fall asleep. I think there is another bad ghost/spirit that is haunting treasure. I also think that this bad ghost is possessing one of them. My guess is Doyoung. There is a female ghost that haunts people in school that is connected with class 4, she is a bad spirit that got disturb by one of the student and she is possessing him, and that is Doyoung. Doyoung because he's an easy target, he has negative energy around him since he's jealous with Jaehyuk (bad spirits/demon's food is our negative emotions). The reason why this bad ghost is only messing with Jaehyuk (so he couldn't focus on study) since that was Doyoung's evil desire. Remember during a call with their professor when he shows this sly smile when he knew that he will be gone for 15 days? But then he was shocked because he basically don't know that there's another ghost (haru) that is messing with his plan. So Haru is protecting his friends. Haru is like Casper, the friendly ghost. The guard I think is the red grim reaper in Sahi's painting. He was there to collect Haru's soul but maybe Haruto ask him that he first want to make sure that his dearest friends are safe from this bad ghost before he come with him and finally bid goodbye. Edited: Let me just add this another evidence I found that supports Doyoung being possessed. 1) Remember when he was taking notes on episode 2? It was written there "How can I get new red pens?". Was it just coincidence that the female ghost that is messing with Jaehyuk does some scribbles using red pen on Jaehyuk's notepad to distract him? I guess not. That's sus. 2) When Junghwan was investigating using his ghost detector app. The ghost appears from Haruto's seat. Which means that is Haruto showing his true form to Junghwan so he will get more subscriber but then the ghost disappear. Then when Junghwan pointed it on Doyoung's seat, a ghost/spirit appears again and it attacks Junghwan (I guess that is another ghost, which is the evil one) then after that, it goes outside the room like it was chasing something (I think it was chasing Haruto). So basically Haruto goes outside to follow Junghwan because he sense that he maybe in danger.

Junghwan and Doyoung is so natural in their acting. Give them their own drama.

So Haruto is the ghost IN Treasure and the security guard can see him because maybe he was once a student who treated him kindly when Ruto's still alive. But! I think there is still another ghost WITH Treasure. The one that is bothering Jaehyuk. Because we all know that Haruto is very caring especially to his roommate. Now I'm excited for the next episode! And lol I didn't expect Asahi's character. Everyone's acting is so good! Kudos to Treasure!

Don't worry Haruto you're the cutest ghost I have ever seen in my whole life.

Haruto's eyes speaks thousands of emotions. If he wants to pursue acting and be an actor, he can be one. Another plus is that the camera loves him, in every angle, Haruto looks amazingly good.

I love haruto's character here, he's so caring. He's literally like a guardian angel of the class 🥺

haruto is a nice ghost. he is friends with everyone. so he will never hurt them.

*"once you entered this fandom, there's no turning back"* - teume 2021

My theory: There's already a foreshadowing on the first episode on the List we noticed that his name is on the last list. Also I noticed that his eyes are different like grayish, when hyunsuk said that ghost can't eat red beans he immediately eat the scramble ice but not the red beans, also Jaehyuk said that his nightmares start on March when he moved on their dorm that's also the mock exam day of all students who passed the exam and the teacher noticed that Ruto's mock exam on March was missing. On yedam's evaluation song i think it said that 'naneun salyojwo' means 'please save me' And it all make sense, also the guard knows something about haruto, also I think there's a killer. BUTT!! WE STILL DON'T KNOWW~ THE TWIST IS ALWAYS AVAILABLE HAHAHHAH.

Since ep 1 Yedam really showed how good he is even with acting. His expressions are on point and his line delivery is very natural. An ace indeed. Actually, everyone did well.

Jung Hwan should be afraid of the Security guard... but the security guard scared of junghwan funny LMAO 😂😂 😂😂 😂😂

I truly believe that HARUTO is not a bad ghost,he will never hurt his friends!

haruto is not a bad ghost he is a kind and nice ghost.. he really likes his friends and doesn't want to hurt them :/ but that long haired ghost scared tf out of me

asahi's black hair was his best look, i hope he brings it back >

Breaking News: Haruto is Nominated as "MOST HANDSOME GHOST OF ALL TIME"

Haruto is definitely not the evil ghost, he just wants to be with his friends. I bet he’s even trying to protect them.

I'm so excited for EP.3!

Junghwan's acting skill is excellent. So natural. I won't be surprise if one day he'll be one of the main cast of a kdrama.

no because treasure can literally debut as actors, not just one member but as a whole group. I know I stan a group with overflowing talents and that's a flex.

That's why Haruto is always chilling meanwhile Jae is studying, he doesn't need to worry about grades and university lol. They're really good at acting, I hope all teumes can enjoy every episode as much as I do.

We all know the story doesn't end with Haruto being revealed as a ghost. THERE'S MORE TO IT AND THAT'S WHAT MAKES ME LOOK FORWARD TO IT MORE

omg doyoung and junghwan's acting during the fight scene was SO good despite the fact that they're not even actors. i'm so proud of them

Let's talk about How damage Asahi's words to us when he said "Baka janai no!" Cool Asahi PERIODTTT

My theory is that HARUTO is a good ghost who is only trying to protect his friends from someone who can harm them. It might be a bad person or bad ghost but my crazy mind really thinks that DOYOUNG is the bad person/ghost because of his ambition to study abroad, he kinda do whatever he wants just to get it and might get rid anything that comes his way. Also, JAEHYUK is the most troubled among them by the ghost as he is studious and intelligent. DOYOUNG might be seeing him as a threat that's why he tries to sabotage Jaehyuk's sleep and grades. Lastly, Doyoung could be a ghost as well as he was able to trouble Jaehyuk or whatever. TREASURE's acting are so good and refreshing again! 💙

Junghwan acting since his childhood and is still slaying shows how much a great actor he is in a such young age

If Doyoung is really possessed by the bad ghost, him saying "YOU BE CAREFUL " to Junghwan might be a threat. He might be the one who'll be bothered by the bad ghost next.

bruh why is nobody talking about Doyoung?! HIS ACTING IS SOOOO GOOD, THE FACIAL EXPRESSIONS OMYGOD?!

For non-fans, after watching the web drama. Please check their songs. You'll see how talented they are. In short, Stan them!

when u r not a teume but u watch this web drama and u need to memorize their name lol 🥲

Asahi saying "I was praying for our class and this is what I get for return" is screaming for Sehun's "Before I go to bed, I always make sure to pray for you all. Why are you all ganging up on me?" I can't ㅋㅋㅋ

10:42 the way mashiho just goes “he said what an idiot🙂” is HILARIOUS to me

can't believe it's the total opposite. junkyu is not scared of horror and ruto is. they're so cute ㅠㅠㅠ

하루토가 귀신이라는 사실과 아사히가 자신이 귀신이라고 말한 그의 반응은 매회 보는 내내 설레게 만든다.

Park Jeongwoo, Park Jihoon and Kim Junkyu character is bringing this whole drama to the another level.

Let's talk about Yedam's acting skills,he's such a natural actor!

We can't deny the fact that all the Treasure members are so talented in everything, Treasure never disappoint us.

I had to rewatch Doyoung and Junghwan arguing scene because it was so good and intense 😭 I'm actually impressed by their acting. Doyoung looks scary but damn cool when he's like that

so, nobody's going to talk about Jeong-woo singing love scenario while taking a shower for him to not be scared sscsfsgshshsh cutie

HARUTO IS AN ANGEL GHOST

I’m so proud of Yoshi. His acting has grown so much.

and jeong woo singing love scenario in the shower just as me...relatable...

Jihoon: Haruto, I know it's scary but don't cry, okay? Me: *remembers the tmap ep where Ruto cried*

If haruto is the ghost,he's the most handsome ghost in the entire world.

I couldn't believe Asahi is the one who prayed for them lmaooo

They are literally looking for the ghost, but he's with them all the time. 😂

THEORY: Haruto seems to be a nice ghost though. He just wants to live again. He even helped Junghwan get more views. He's so sweet to Jaehyuk as well and everybody else. He is also fulfilling Hyunsuk's (our ghostbuster leader) dream to actually find a real ghost. Haruto is Casper the friendly ghost hahaha. The security guard knows something. He even smiled after seeing Haruto having human friends. The ghost with the long hair with Jae, I think is the bad one. She's keeping Jae awake most of the night that's why Jae got a bad mark on their quiz. Haruto is kinda protecting them from her??? He's even giving Jae some tea to help him sleep. I don't know.

Y'all apart from their acting skills, visuals, and their confidence, the storyline is worth pointing out. This is the rising action/part of the story where we see individualistic roles of each character. Apart from the ghost conflict, his induces conflict between the personal goals of each character, especially Junghwan and Doyoung. Yes, Doyoung and Jaehyuk are the rivals, but we can see how the pure intention of this KZbinr to gain followers and have youtube success go against the aim of Doyoung to let the issue stay inside the class. Junghwan wants youtube followers, but the best avenue for that is about the ghost contents. He will be pushed to be active about finding the ghost and in keeping the issue alive because its the point of his new contents. Doyoung on the other hand, wanted the issue to be resolved by them and not let it came out because having problems in the class makes him think about the consequence and bad remarks he can get from his teacher, which might later on void his application to the new school. Both are personal agendas that clashes. This might not be highlighted a lot but is a good side story to tell. Asahi on the other hand is an ally instead of an enemy. ASAHI and YOSHI would definitely play an important part soon. As for Haruto, I think he's not the type of ghost to purposefully do evil stuff. He might be a former student who d*ed there. But I'd like to know why and how did it happen. What is his purpose of being in that specific class? I think, now that we know who the ghost member is, the story would now revolve around the characters' individual story and how significant Haruto being a ghost as classmate/friend of the students in class 4. The things we are yet to decipher are: - Junkyu and his gf. The hair hovered behind Jae is long, and so far the only significant yet non-existent female character is the gf. This is a stretch but its possible. - Junkyu's secret. Junkyu took selfies with Haruto, but do ghost appear on photos? Is junkyu aware that haruto is a ghost? - Jaehyuk's character build up. As much as he appreciate Haruto, his situation pushes Haruto away. He did not intent to harm Haruto but if Haruto find out that there's a talisman there then maybe he'd feel upset and betrayed. - Asahi's contribution. He seemed so sure he knew it was Haruto... Why? And how is his art coinciding with what's happening like the crow and red in it. - Doyoung's control. How much can he control the happenings in the class until he get a job well done to the teacher? Is he going to take it far? Or has he?

Haruto's acting skills are no joke,his expressions are on point.

All the guys in this drama are friekinlly handsome❤🎉💜💝

Haruto is a good ghost. He didn't even hurt any of his friends.... Hes an angel ghost!! Maybe there is a bad ghost trying to hurt Jae Hyuk and Haruto knows and he's trying to protect them?? We'll have to wait and see!! Edit: TYSM FOR 1K LIKES~!! (I don't think any of the other members would hurt each other if they were the ghost)

DUDE THE WRITTER, PRODUCER AND TEAM REALLY PUT A GREAT EFFORT FOR THIS, THEY LITERALLY GAVE OUT EVERY SINGLE DETAIL AS A CLUE NGAJSBSK

YG: "lets just reveal who's the ghost so they won't make any theory this time" Teume: *proceed on making theory about the bad ghost one*

이게 왜 이렇게 신나는 거야?(⁠ᗒ⁠ᗩ⁠ᗕ⁠)

SEE DOYOUNG’S EXPRESSIONS WHEN ANGRY TO JUNGHWAN!!!! HE KILLS IT!!!! 연기도 표정이 진짜 잘해!!!!!!!!😍😍😍😍

I think almost everyone agrees that Haruto is a good ghost, I will put my trust in Haruto

doyoung's acting skills is so good at this point and imagine if he officially debut as an actor. he's effortlessly good at everything and very natural. his voice toning, eye contact and facial expressions speaks alot even if he has few lines. and that's how great actor that he is. very talented!

I started watching ''Mysterious class'' again,because I love TREASURE and this drama so much😆 All of the members are such good actors!!!Junghwan and Doyoung really shocked me here...in the drama they hate each other,but in real life they are like siblings and love each other a lot😊

Let’s all appreciate the teumes who were smart in knowing and acknowledging haruto as the ghost . Hats of to you guys and girls and fighting for the next episode!!

I had to pause and laugh for a minute when Doyoung argued with Junghwan and how he push Hyunsuk, Yedam and Mashiho. Their reaction was so funny. All the hyung line be acting like a kid in this web drama and all the maknae line and middle line be acting cool and scary.

don't get bored of watching it again❤Asahi here is still quiet🤣

this might not hold much validity but the fact that my mom is watching this with me, and that she knows 9/12 of their names already, that she’s so hooked on this webdrama; she keeps asking me when is the next episode, and keeps making theories with me - means THAT’S HOW GOOD THESE BOYS ARE WITH THEIR ACTING, a fully grown adult got interested with them and is patiently waiting for the next episodes. Treasure worried that their fans might not like this webdrama but in reality they are gaining more fans with this.

When you realized that you stan 12 talented boys like they all can sing, rap ,dance , produce music and act.

haruto is the ghost. oh my gosh. it all makes sense now. he ate the beans like a he went on a hunger strike, purposely said hi to the guard, and makes sure his existence is known to everyone. in addition, he went out when junghwan was live streaming. omg

Do you want to believe me that they are idols and not actors? If I hadn't knew them before then I wouldn't even have guessed them being an idol

I'm just so amazed watching their actings. They're giving justice to the roles that they've given. Beyond proud especially to Haruto, Jwoo Junghwan and Yedam. Not to mention Dobby, can someone cast him for kdrama or give him award?!! Our maknaes never failed to surprise us. Hyung line are damn great actors too! Stan Treasure coz u're missing half of ur lives!!

I don't know how many times I had to rewind the argument between Junghwan and Doyoung. It's so good .

If you stumble upon this webdrama without knowing this kids are indeed singers in an idol group, well, you'll think they are real actors and that's their profession but hmm sorry to make break the bubble. They're indeed natural born artists!!

Haruto s facial expression is no joke His eyes expreonss so much emotions loveyou Haruto

Jihoon is the happiest person in these 3eps coz it gave him extra chances (from what he normally do in real life) to tease Junkyu and Jeongwoo a lot here!!!

OMG, these kids are getting better and better... As someone who have watched them since they were introduced as YG trainees, im soo proud to see how they are growing up to be great in what they do.

Haruto's acting is getting better and better every episode and i'm here for it, damn those visual thoo

이 영상은 작년에 이미 봤지만 이 드라마가 좋고 재밌어서 매번 여러번 봅니다 😅😅

Treasure actors really hits different their expressions, acting is soo damn natural and even haters can't deny it

This episode gave us some answers but left us with more questions honestly and also Haruto seems like a good ghost, I mean he went after Hwanie to proof that there is a ghost in their class room to help him have more views and subscribers.

*Junghwan's acting skills and facial expressions never disappoints.*

I've already seen half a world of comments and I don't see anyone talking about how good Yoshi is at acting

it was so fuuny that it turns out asahi is just scared of the ghost that his hands and feet started to get cold ㅋㅋㅋㅋㅋthis horror genre is turning out to be really funny ㅋㅋㅎㅋㅎㅋㅎ

"Bunshinsaba is the ghost of a dead person who can come back to humans’ world and answer people’s doubts." As you all know bushinsaba is their concept right in the firs episode. Now that we all know that Ruto is the ghost, maybe he was just there to help out his classmates and not to cause harm. Jaehyuk having trouble sleeping, he keeps thinking on why he cant sleep or keeps him focus so Ruto keeps getting him different types of tea to help Jae. Another is Jeongwoo being scared of ghost, you can see that there were no interactions between the two. Another is when junghwan left during their movie marathon, Ruto follows, as junghwan has been having trouble creating new content for his youtube channel so he decided to share out ghost story in their school where ruto might be the one who showed up in the middle of his shoot and capture him. To add, when the ghost detector faces at the back the ghost appear in ruto's seat. But things might not go well as he planned. Maybe we have our focus now on ruto after the revealation of the ghost but I think there's something deeper about this. Maybe another ghost roaming around??? hue why does the episodes are getting short yg I cant with your endings!!

Since Hwannie and Dobby's heated argument looks realistic and I find it scary, I wanted to imagine *Som and Podong in an argument* . And now I can relax. LOL

until this ep, I only recognized Haruto, Junkyu, and Yedam faces! it's so hard to memorize their faces 😭

ep.3 유령이 있습니까? 점점 재밌어지네요 😭🔥🖤😼

Dobby, Hwannie, Yedam, and Ruto stand out in this episode. The boys did a great again 😭🙌👏

I just wish the episodes are longer. It's fun watching them acting.

너무 재밌는거 아닌지 감사드립니다 트레저 열일 정말 너무 고맙습니다!!

haruto is not a bad ghost, he just want to have friends. it seems like his former classmates bullied him until he die

Let's appreciate Haruto, his acting is on point, not exaggerating to portray his character as a ghost. Not much dialogue but he showed so many emotions and we can feel it...

Ohmygosh. Who ever guessed last episode that Haruto was the ghost is a freakin genius and a good observer too. You can see his theory in the beginning of the CS in episode 2

Personally think that Jeongwoo, Hyunsuk, Junghwan, and Asahi have a lot of talent in acting-

As expected the drama is getting more exciting. I am really amazed to Junghwan and Doyoung's acting and also other members did great.

Junghwan is such a born actor,his expression is a killer

아아 진짜 무섭다고 너네 왜 연기 잘해서 몰입되게 만드는거야ㅠㅠ 나 귀신 이런거 진짜 못보는데 에라이 설마 진짜 무서운 분장이라도 하겠어..? 하면서 매화 챙겨봄.. 근데 이렇게 미스테리 생기는게 더 소름끼쳐...ㅠㅋㅋㅋㅋㅋㅋㅋㅋ

왜 잘하고 왜 재밌지..?

Congratulations YG for successfully drifting our attention on TREASURE'S upcoming comeback through this webdrama

We know how talented Treasure is but their acting in this drama is really beyond expectation. They nailed every scene. That fight between Doyoung and Junghwan. The tension! I’m so proud of these boys
