Oh also I'm angry with the ML but it's true the plot is actually interesting. Just that I feel it's unfair the MC has to go through this sighh...
I also think the blond is obviously inlove with the uke and that it's all just because it took him 10 years to finally grow a pair... But I can't say I blame him for that, given that when both were still students it would have been a lot harder to bear the risk of entering a relationship that could ruin the peace within your entire family, and maybe even make it look like he was just a white privileged rich boy taking advantage of his superior position to force himself on his adopted and underprivileged, non-white step brother... Now that Jin is older, and a working and somewhat economically self-reliant adult, they're both on more stable grounds now to withstand those judgements.
True that's a different perspective however.... hmmmm I don't think it's right to disregard his womanizing habits within those 10 years. He didn't even try to change or maybe didn't try enough. I guess he was more afraid that his beliefs were breaking rather than realizing that he could finally pursue his real love. He has the power and the right to be true to himself but he ignored it for years. We have to remember he is an excellent, popular and rich person. Truthfully if he tried to resolve things right from the start when he realized his feelings then wouldn't the risks be lower? It's because he has the even more power and exposure now that things are more risky. I can't help but think it was a way to keep Jin away but he couldn't help but feel annoyed when he does. So they got stuck with such a situation. That's my opinion though we can't be too sure if there were stuff behind the scenes so I can't say I'm right. It's just what I've deduced for now based on the few chapters.
Also we can't really force our thoughts and beliefs on someone else. Maybe he has some emtional scars himself that's why this has dragged on. We'll see more when we get to the later parts.
WTF???? Piece of shit asshole I bet he's really in love with Jin but continued to deny it that's why he became even more of a womanizer. I think he wanted men to not be near him but couldn't help but feel annoyed that even Jin was going away from him. Jin has gone through so much if he doesn't even have a shred of responsibility in him then don't toy with him. Just like what Evan has said, it hasn't been easy for him and he needs a quiet and peaceful life with freedom from the press. If you were really serious then do your best to change. If not then don't hurt the guy he's gone through enough already.
