In the new chapter 68, the Korean raw.
The roles changed. Jihwan takes the role of Gyujjin, and Taehee (the guy with piercings) takes the role of Jihwan.
Jihwan told Gyujin "He was in front of you this whole time, and you weren't able to get some". Same applies to Jihwan, he already had the heart of Sooyung but he had to ruin everything because he got stupid.
In the last conversation, when Sooyung confronts Jihwan about what he did to Taehee (hurting him). Jihwan repeats the same things as Gyunjin.
Jihwan feeds and forces his delusions of living together with Sooyoung as if he agreed to that. Same as Gyujin did in chapter 12
Sooyung tells Jihwan that he prefers to live with Taehee than him. Same as he told Gyujin in chapter 11, He said he preferred to stuck with Jihwan than him.
-Sooyung thinks that Jihwan uses the same tone of voice and has the same vibe as Gyujin, even repeats the same words in Chapter 14 and chapter 31.
Gyujin kind of warns Jihwan about Sooyung. He told him "Sooyoung is good at toying with people and refused to put the whole time" Of course it is not Sooyung's fault. Just that the two guys got obsessed over him and feed more their delusions.
The difference between them is that Jihwan is the ML and he is going to end with Sooyung because the author put the tags of #RegretfulTop and #RunawayBottom and the author said she loves unhealthy love. Also Jihwan doesn't hurt physically Sooyoung, just mentally (both are bad).
My conclusion is that Sooyoung kind of attracts the same type of men, maybe he has some daddy issues.

MY PREDICTION FOR THE ENDING..
TRIGGER WARNING
This is how I think Jihwan is going to regret and have a redemption arc. Sooyoung is going to try to commit su*cide himself and maybe almost accomplishing. So Jihwan is going to start "feeling" how his father felt when he lost his mom. He will regret and stop being so controlling and happy ending for everytone

It's amusing how Jihwan is unknowingly following the same path as Gyujin. We have limited information about Taehee, but in the raws, he gets injured, undoubtedly due to his connection with Soo Young. Taehee's decision how he’ll handle this predicament will reveal his significance to the story and it might also indicate whether he can be a formidable rival to Jihwan.

Spoiler
I suggest to read the comic because at least the novel was good and enjoyable. This spoiler is just for the spoiler lovers like me.
The plot is similar to Can't think Straight. They start as enemies with benefits.
Kyuho--KH
Yoongun-YG
-Many things happen at the school and they start connecting and sleeping more often.
Kyuho confesses but gets rejected by Yoongun (he still wants to be fbuddies but KH doesn't accept because he has feeling for him).
-YG asks to be fbuddies again but KH rejects him, telling him that he likes someone else (he was lying).
-KH gets in trouble in his new job as journalist but YG helps him.
-YG couldn't accept KH being with someone else. YG created a username with the datingapp and tried to match with KH.
-It takes a lot of time for Kyuho to accept Yoongun again but YG really insisted until he got really drunk and bang his door begging.
-They start dating and Yoongun introduced himself as the boyfriend of Kyuho. They are a sweet couple now.
I translated with MTL (Google chrome translator so I lost half of my neurons trying to read it)
This is an spinoff of another story called Dating class/Dating business where the protagonist is Moon Kang, friend of Kyuho. He later appears in this story and Yoongun is jealous of him.
Moon Kang (chapter 17) is the bottom of his own story and is more in the drama side. His best friends are Kyuho and the other girl.

Spoiler...
No, the confession part hasn't happened in the raws. They go to a trip.
The manhwa righ now is in chapter 3

Ohh why you think that? Tbh Maybe my narration wasn’t the best. I just wrote the points I remembered the most. The novel was in Korean and every chapter of the novel is very long and other things happen that I couldn’t fully understand. But I can assure you the MC has self respect if you are worried about that.

I have another crazy theory!! sorry, I woke up with a vivid imagination, even doesn't make sense
What if the first crush of Doyeon is Daehyun and he likes him and wants to boing him in every part of his apartment?? And he returned to Korea to get him and why not? and he can learn he is bisexual so his fantasy is completed.
There is going to be an anime related to this series. But why it looks like this one is unpopular The anime trailer looks good. Where is everyone? XD
youtube.com/watch?v=_vIT4pE-8as
There is indeed the anime though it's 80s anime,too old ,Gegege no kitaro.But the new one is just a movie about the mc father and his friend "the birth of kitaro" for 100th anniversary of gegege no kitaro
Thank you for explaining!!! I was just curious about the movie because I like youkai animes and I felt sad that no one was here, even if it was old. I would definetely check both.
Totally recommend the movie.It's already out.And although it's tragic,the friendship make people cry.And the movie explained most of the original lore too so it would easy to understand even if you didn't watch the gegege no kitaro anime series
