What if the black haired seme from the past and the white haired seme is two souls in one body? Thats why the white haired only comes out at night in the flash back? It just doesn't make sense, because at the begging of the story. The uke was crying for the dead black haired seme in his dreams, he also seems to like the black haired seme so idk im confused.

I think it makes sense, just some parts haven't been explained yet since season 1 didn't focus on the plot and more just teased readers. The white haired and black hair are not two souls in one body at least in the past, its shown they're different people since we see black hair spying on kwon and white hair. The beginning of the story is not yet explained as the story hasn't finished yet, so that part is unanswered.
Ooohhh~ building up angst i see
The angst has been building up since the beginning, LET THAT BASTARD SUFFER.
