Mentally Unstable Occult (Yandere Tokyo Revengers x Male reader)

A boy born into a different world, still remembering his old life. The torment of it made him go insane. On top of that, he can see and talk to ghosts now? How in the hell was that possible? Nothing made sense to the boy, but it never did, really. Now he has to navigate this life, knowing the future outcomes of everything, but not being able to tell anyone. And having to deal with the multiple attachments he's acquired, both in his past life and his current one. And not only spiritual attachments.

Will this be any better than his previous life?
