I have a idea of why Kwon is "cursed" in this life back in one of the previous chapters there was a flash back and it had to men and another guys shadow behind the door based on the I think that Kwon is cursed because he "cheated" in his previous life
I would not say cheating maybe someone that loved him but they did not share the same feelings and cursed him. Like a friend that loved him but kwon loved ml and the other one hated this so cursed him so in there next life they will actually be together but sometimes history repeats itself
Its good but why man every manwha i read that has a toxic ml the mc always falls in love with them like no! Go for some one else! Tbh if I was the mc as soon as I was reborn and met ml I would've killed myself since it would be better not to go through the hell that happened in the previous life
he said he's gonna kiss his father if they didn't stop
