Okay I hear you but what if jooin did love cain back but it was forbidden. And now cain, like you said, reincarnated and went to Korea to find jooin and finally be together. But when he saw that jooin already had somebody, cain decided to just be content with jooin being happy because he love him so much.
ok that makes sense lol
okay but what if cain is jooins guardian from a past life or something and in that past life he was in love with jooin but jooin didn't love him back so he did something that made him able to reincarnate to protect jooin and make sure he's happy
its pretty dumb but yea
