Hi, some time ago I think I read a manhwa where mc transmigrated and had seven years to grow up before he met the villain of that world and once he met him he was overcome with the urge to kill him. Later on it turns out it wasn't his first life in that world and the villain (ml) already killed him in his past lives when he tried to kill the ml. One of his previous lives was as a help in the house and from what I remember male lead's uncle or butler helped eliminate him in his previous lives. Also I think his first life after transmigration was as the male lead's older brother, and I think they were royals.
I would really appreciate if someone could help me cuz it's been bugging me for some time and on cannot find it anywhere •ᯅ•
