Huh

CMIIW but, Taejoo only got together with the insecure new bf because he thought he sexually assaulted the guy, right? He got too drunk because he's so helpless looking for Yoon, and next thing he knew he was in bed with the new bf. So feeling guilty, he said he'll take responsibility. Idk, I don't hate this guy at all.

He was an ass to Yoon esp when Yoon just woke up from the coma but I feel he's trying to convince himself he made the right decision on giving up on Yoon. He prolly thought he's indebted to new bf as well because the guy was beside him through it all, when we all know new bf is just manipulating the emotionally unstable Taejoo. I hope he breaks up with the lying, manipulative guy (who knew Yoon was alive) and move on with his life as well.
