I think you got me wrong.
The scene of Chanwoo going into mental distress implies that he likes MD a lot.
Hence why i find him annoying as a character. Because it means despite liking MD, he rejected MD. Because he didn’t realise his feelings.
*not realising his feelings* is what makes me think he is annoying as a character.

Um.... this is actuallly not fun at all. All this time Chanwoo was getting boyfriends. He refused MD and he was getting serious about a new partner. AND YET he gets into mental crisis when he sees someone kissing MD.
Like..... you could have just dated MD if you wanted him for yourself.
Also i feel a bit sad for the random guy. He deserved the be manipulated the same way he manipulated Chanwoo though. But i still feel bad because he put so much effort into something and it all crashed down.
And he lost to Chanwoo, the guy who turns down MD but still panic when he sees MD kissing someone.
The story is still good overall. That new guy made it quite interesting and MD is good too. But Chanwoo was quite boring in the story.
