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?

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

HARUTO IS AN ANGEL GHOST

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

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

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

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

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

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

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

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

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

*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.

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

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

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.

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

I'm so excited for EP.3!

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

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.

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

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

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

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

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!

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

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

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

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.

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

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

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

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

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.

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

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)

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.

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

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

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

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.

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

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

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

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

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.

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

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.

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 😅😅

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

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

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

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

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

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!

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

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

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

1. doyoung is the bad guy, he dislike when jaehyuk is in first place. So, he sent (or asking someone to sent) an evil spirit to disturb Jaehyuk and the rest of his class. Like he wants to have a full control in the class. 2. Haruto is Good Ghost, he only wants to protect his friends. The security guy, have this nostalgic expression when he sees haruto (like maybe in the past haruto helps him). 3. I wonder if Yoshi is the one who sent the evil spirit (by a request), since his grandma is a shaman. As i know, shaman can also send an evil spirit to other people. 4. Is the next target junghwan? Doyoung threatened him tho…

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

KIM DOYOUNG IS CONSISTENTLY GOOD. HIS ACTING IS LIKE A PRO. I'LL NEVER SHUT UP HOW GOOD DOYOUNG'S ACTING WAS. SOMEONE NEED TO CAST DOYOUNG IN KDRAMA, JEBAL !!! THIS KID NEVER FAIL TO AMAZE US !!!

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

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!!

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

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

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!!

Let's all talk about Jaehyuk's acting skills,he's so good and is such a natural actor,his expressions are all on point..

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😊

Even if Haruto is the ghost,he's still the most handsome ghost I've seen.

Someone give KIM DOYOUNG the oscars. all I'm seeing is the class president and no trace of the idol that we knew. He's also consistently in character since ep 1 and stayed in character even when the camera isn't focused on him.

ep.3 유령이 있습니까? 점점 재밌어지네요 😭🔥🖤😼

이게 왜 이렇게 신나는 거야?(⁠ᗒ⁠ᗩ⁠ᗕ⁠)

Hyunsuk : ghost hunter Jihoon : goofy Yoshi : Mr nice guy Junkyu : cutie Mashiho : chibby 🤣 Jaehyuk : smart and serious Asahi : silently knows everything Yedam : the trainee Doyoung: dedicated class president Haruto : THE HANDSOME GHOST Jeongwoo : naive coward hahaha Junghwan : the soon to be one of the host of buzzfeed unsolved with Shane and Ryan 😂😂

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

Jeongwoo singing "LOVE SCENARIO" by iKON while bathing is the cutest thing ever.

너무 재밌는거 아닌지 감사드립니다 트레저 열일 정말 너무 고맙습니다!!

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!!!

I always look forward to Jeongwoo-Jihoon-Junkyu scenes cuz they're so funny 😂😂

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?

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

JEONGWOO IS SLAYING IN COMEDY HIS ACTING IS SO NATURAL!!!!!

Haruto is a ghost but I know he is not the ghost that has been bothering or disturbing the class. Still excited to know more about the story and what will happen next.😆💙💎

영화 진짜 재밌다 이제서야 알았다

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

I don't know why but Hyunsuk's acting has caught my attention since Ep 1. I know his role is just like the usual him, but I'm still amazed thinking that he can still be natural in his dialogue, expressions, and intonation in front of camera

I’m impressed with SO JUNGHWAN’s acting! Seriously he can be a main actor in a Kdrama or movie!

Haruto's acting is different. Wow! He will definitely make it huge if he pursue acting as well. That face truly served!

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

DOYOUNG AND JUNGHWAN's SCENES IS THE BEST, I GOT GOOSEBUMPS ON HOW GOOD THEIR BOTH DELIVERY THE CHARACTER ESPECIALLY DOYOUNGIE 👀🤭 WE ALL KNOW HOW WAS DOYOUNG IN PERSON AND THE FACT THAT HIS CHARACTER IS TOTALLY OPPOSITE OF HIM, HE NAILED IT!! 👏🏻👏🏻👏🏻👏🏻

Junghwan's acting has been so so good in all 3 episodes so far. He really is the actor among the group. I'm also enjoying Doyoung's acting this ep. Actors HwanYoung!

Jeongwoo and Jeongwoo honestly have so much acting potential- as well as being incredible singers and dancers- THEYRE JUST SO TALENTED AH

Treasure aren’t only amazing singers but awesome actors Edit: who is your bias?

Aight, Doyoung's acting is SO SO GOOD. so proud of him.

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

Super King Cow Baby Junghwan is so cute🤗 I really love the way he act.❤

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

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.
