Jaekyung's family or his past might have something to do with su/cide by walking into the sea (or a tragic accident involving the sea), and he couldn't save that person/family. Basically it's LTIT all over again LMFAO
And maybe he was from a poor family or was a weak person himself and he was bullied or getting picked on by some street thugs and that's why he chose to be a wrestler or something because stronk = powerful = people won't bug him and now that he's rich that also means he's powerful = there's nothing in the world that he can't do = he won't need anyone to depend on/attach to.
To which I understand why he became a horrible person (NOT excusing his horrible actions), and this is becoming a cliche plot engine where the ML is a mean mean person until something similar of his past is happening again in the present and suddenly his hot n cold demeanor melts away because he finally shows some concern for the other person. And then he's back at being the mean person again. Like cmon

i love the characters and the artstyle (something about cheolho made me go oh.... I'll be blind just for this once), tho I agree the plot is wild
But like that's the point? Both of them aren't normal (well at least cheolho is) so I think it's understandable for thr plot to be as unnormal as impossible it could be? Plus I see a lot of plotless smut/porn with butchered plot similar to this (or worse than this).
Anyhow I'd like to think this is like one of those author's barely disguised fetish thing LMAOOOO
I low-key live for this miscommunication (build up angst or whatever)
