I'd rather jump in the ocean to get reincarnated than be in this story.

Reincarnation as MC would a whole different level of difficulty in life. From attempted murderer when you were a child, creepy old uncle thirsting after you your whole life and eventually abducting and raping you. Furthermore, getting cursed with being with ML who abuses, rapes you and treats you like a prostitute that he can sell for his benefit.

No wonder dude has addictions, poor kid most likely just copes with his shitty ah family life
