Need help with the name of reincarnation bl pls!!!!

Someone was looking for this on reddit so I thought I'd crosspost it here cause shit sounds interesting!!!

MC (bottom) reincarnates in modern times after suffering all his life. In his old life he was part of the imperial family (historical time) but he was banished (I think) and the emperor (the ML) finds him years later, locks him up and rapes him until MC commits suicide.
In his new life he decides to change but his friend looks a lot like the emperor so he avoids him, runs away from him. But he will get to know him and they will get closer.
Also, the ML goes crazy after MC's death and decides to do a weird ritual that allows him to reincarnate with the MC and keep his memories. Then he pursues the MC in his lives there without ever managing to be with him...
In the most recent life they are still in high school and ML is gently trying to coax the MC .

This is all that the OP remembered. Please help!!!!
