I pity him too. And the fact that he's trying his best in the new relationship caus he thinks he r*ped the other dude so he wants to take responsibility by doing his best in loving him.
He knows he still has feelings for Yoon but he's pretending he doesnt cause he knows it would send off his current bf (who tbh is toxic just cause he is taking advantage of Taejoo's sympathy instead of being truthful and building a healthy relationship from there... he's manipulative, not intentionally per say, but he is). We all know that if Taejoo didnt get drunk that night he spent with him and misunderstood what had happened he might have been actually able to move on from Yoon instead of forcing himself to. But since he's forcing himself, he hasnt truly moved on completely and now we're stuck in the angst loop.

I don't blame him cause he breaks up with MC, I blame him for how he just throws the MC away and was so insulting and disgusting to someone that just woke up from a FUCKING coma! he never even consider how sick and suffer the MC was and just kept being an asshole every time they meet! so no, I have zero care for the asshole! he could have breakup with him in more human-respectful way and not blame the guy for being in a fucking COMA!!
Seriously why everyone is hating Taejoo. If im in his position i would be confuse as hell !!
When taejoo is trying to forget, move one, and fall in love with new person Yoon cameback. It's all just timing so im not blaming Taejoo when he react like a jerk to Yoon, he is trying to focus on his relationship now with his new Bf.
I bet if Taejoo breakup his new bf to be with Yoon all of the people will say that he's a jerk to leave someone that always beside him when he is depressed. So whatever he do he would be the one to blame. I kinda pity him ┗( T﹏T )┛
