I'm sorry but i aint picking nobody side when it comes to this relationship. Taewoo used the boy as a fucking rebound after loosing the blonde uke (i forgot his name) he do be using ppl. And youngwoo or whatever, hes fucking mental, selfish, desperate and annoying. It's one thing to be sad to know the person you loved the most using you as a rebound, but its another thing to be obsessed with someone that much and be that desperate to be by someone side when they dont want you. It hurts to know that ur lover love someone else, but you can't ways keep a bird caged and expect it to be entertained. Let it go and find someone who will value you.
Last chapter i said "watch as xai xu was the actual heir" AND LOOK!
