I get it, he's frustrated because he's been pining on this dude for a long time, but isn't it more pitiful and fruitless to rip that person away from the one they love and force them into a relationship; a relationship where in YOU yourself won't be loved by them either way? I feel for him, but at the same time like, man. Get yourself someone else cause it's not worth it.

I hate but like...I mean he's still somewhat redeemable if the author works the redemption arc right...and also introduces him to actual therapy because theres a lot to unpack in that guy's brain. A person's past doesn't justify their actions but the way they mend those actions through their present choices can at least help them be better in the future.

And this right here folks is one of the best examples of a disguised toxic relationship. When you come across it, you might double think and ask yourself if you're just overreacting but 99% of the time your gut feeling is right.
Anyways, in all seriousness this is probably someone's life rn, getting put down repeatedly indirectly while believing their partner is doing it for their own good
Hm what if his past husband was the dead shin yooyoung and 'our' shin yooyoung is the white haired boy (obviously)? Then that would explain why he hated og SYY sm bc he was abusive towards Kwon in their past life, maybe SYY did something to the guy out of anger and Kwon got implicated in it which explains why he's guilty towards Kwon. Maybe it even led to Kwon's death?
Its either that or they take the yandere route. He kills Kwon's husband and imprisons Kwon for himself. When Kwon dies he binds his soul or whatever so he can follow Kwon into the next life. Bc we still have the supernatural factor to take into account, and the fact that ML was previously called a 'curse' or 'goblin'. That means he might have some unusual abilities.
I like your theory! It makes a lot of sense and gives the readers a clear team. I would die inside if it was swapped, because I like the white haired goblin boy from the past life.
Plus their names being similar including the family name makes me think it’s a bloodline thing. Maybe they were bound together in a past life, which is why Shin Yooyoung was drawn to our mc. Then he gets hit by the truck and dies, then our white haired past life boy takes over. Those 2, the young master and goblin from past life, seemed to have something up. Might explain why the goblin was able to take over his body.
