So you're gonna tell me in a country like south Korea, no tabloid or paparazzi ever dug into the past of a superstar like JK? Yeah, right Mingwa..

I mean he is basically an orphan with zero friends who know anything about him, also he wasn't local from seoul but a small far away town, so it kinda make sense... and he ain't a kpop star but a sports champion so the paparazzi would have different things to write about? skills maybe?... and it's not like every superstar's life history is broadcasted out loud, some do have a past no one knows about irl... but yeah, idk man

He didn't have friends, but he tagged along other punks and criminals, one of which also became a MMA athlete. And when tabloids want to dig up a scandal, especially in Korea, trust me they are capable of anything.
Having a superstar be a former punk, who beat up people in the streets and possibly affiliated to drug dealing? You're so screwed, you're career ruined at the speed of light!

It's somewhat true, but he is already infamous for his temper, his past wouldn't have even matter that much lol... and although i get your point that he was associated with bad peoples in the past but for his stature in a especially violent sport wouldn't have intrest anyone to know about his past or something... but yeah whatever, as long as the story progress in a good direction I'm cool with anything.

Honestly this character development doesn't make any sense. A person that had such a childhood and knows what it means to work hard and build a fortune from scratch doesn't treat troubles people like shit.
Jk should have resonated with Dan, since they kinda share a difficult start, instead he treated him like he was a worthless peasant.
If you know what it means to be starving you don't throw away an expensive gift, like it's nothing.
This sob story is only here to try to live people, but on a narrative point of view is complete bullshit..

You're wrong.
1. Ppl who grow up in awful situations grow up to repeat same patterns if behaviours that were mirrored around them, we literally see this in real life all the time. Empathy is learned not innate, and if it's not learned, you get awful people.
2. He didn't throw away Dan's gift bkoz he's soo rich and it means nothing (he didn't throw it away at all). He rejected it bkoz of the emotional implication of Dan buying him a birthday present and was angry that Dan was crossing the emotional boundaries he had set. He literally donates the birthday presents he gets from fans, what??
3. He didn't treat Dan like a worthless peasant. He rightly pointed out Dan's horrid living conditions (bkoz he's literally familiar to it) and literally took him out of it.

Hmm IDK trauma comes out in different ways, some people end up like you've described, but it's not all one size fits all. I think the bigger issue is that JK doesn't relate. The way Dan feels about himself vs how JK feels about himself differs. Their thinking is different. When JK life was ass, he was constantly thinking about getting OUT of it. Dan, on the other hand, was focused on getting THROUGH it. I think that's where his issues with Dan lie. I think he finds Dan's attitude very nauseating. Dan is someone he can't understand. Like yes life's beating your ass but STAND UPP 'because that's what I did so why can't you' mentality. (I'm not a JK sympathiser btw he's been absolute dookie trash) I have no explanations for all the crazy things he did other than that man is built on spite, that's what's got him this far, and it's done him more good than harm... until he met Dan, and now it's blowing in his face, rightfully so :)
People saying that Hikaru didn't like Yoshiki in that sense, jokingly calling him gross and making appreciations about girls... Are you really sure that was not a forced mask he put on to hide as well? Let's not forget his last thought before he died was Yoshiki.. he could as well have been afraid to let his queerness slip, just as much as Yoshiki did.
