But he didn't cheat on him. He frantically searched for him and destroyed himself for 5 years and when he was finally moving on, five years into a new relationship that he was forced into because he thought he raped the guy, they guy who he mourned for suddenly shows up out of the blue and think everything can go back the way it was. He was a supreme dick about it, but I certainly feel for him way more than I feel for Kwon.
They weren't. They used to talk a lot because they were searching for Yoon and Kwon was helping them since he was Yoon's supervisor who knew where he was stationed, he was their direct contact to his job where Yoon got lost. Yea he got a new boyfriend after he couldn't find his missing boyfriend for 5 years. You said he was cheating before the accident and there is no evidence of that in the story.
i think taejoo he feels guilty lol.. come on taejoo just admit to yoon that you cheated on him before he the accident war
