Actually, given how he's always been forced by Taeyoung's cousin every time he's had intercourse with him, I'm pretty sure those are not the first times he's forced him. And I'm pretty sure he's not the first person to force him. So yeah your complaint that prevents you from liking Wonho (while ignoring the fact that he has raped Min-ki, himself, suggesting that you think that cheating is somehow worse than rape and that being raped is a form of cheating) is directly addressed in the story, itself, unlike in most other cases where we're only provided with excuses for an actual sh!t character's behavior. And, in this case, that actual pos would be Eunwoo, who needs to die a thousand deaths... even though no one ever says anything about him. Wonder why.... Actually, no, I don't. Ktbn.
In the raws the president of Wonho agency says that Eunwoo asked for Wonho... Wonho certainly accepted in exchange for jobs... What comes after that does not matter much because yeah... He accepted that shit for fame...
Now the cheater becomes a victim... He did all that for his benefit, not thinking about Minki feelings, he was not forced to do any of that, in his head he needed this to continue in the media, my support he does not have. He caused all that is happening, now he has to endure.
Sad to know that there are people who support a shit character like that... bleh whatever (〜￣△￣)〜
