Exactly, Seungho has most probably fucked his entire "friend" group but of course you always get that one that catches feelings and is so majorly dickwhipped that they suffer under the delusion that they are both special and irreplaceable, clearly Jinhwa is neither. Seungho only started fucking him again because he really wasn't in the correct position to go after Nakyum, notice that after Seungho and Nakyum are together that first time he neither participates in orgies or seeks out others for sex.
1) he’s is a arrogant prick who looks down on others just because their are so called “Low born” like WTF. who cares? We’re all going to die eventually so why waste it on judging other people like that?
2) He throws tantrum like a spoiled toddler. Like when he split the water on the painting . Or when he strangled Nakyum, even when he hired the assassin.
Like if I had to sit down and talk to him I would say this “I am going to ask you what my mom ask me when I did something wrong. Was it worth it? Tell me when you purposely poured Water on the painting, to not get the results you’re looking for, was it worth it? Or when you strangled another Guy out of jealousy to only get bet and humiliated.Was it worth it? now you hired the assassin, now tell me do think it will be worth it? Because to me it seems like a big waste of time.”
3) He jumps to conclusions.He never once asked Nakyum what he thinks of seungho. He just assume that he was trying to seduce Seungho.
