I feel like Sangwoo will kill himself or he would kill Bum, because of their promise, maybe Sangwoo would end up killing himself because he wants Bum to himself, then due to the promise-thing Bum ends up taking his life(?) And Sangwoo keeps on bringing up their promise, and marriage. Idk but I feel like the ending would be somewhat like that.
