Does anybody know the tile of this manhwa where the uke looses his memories and he thinks the seme is a psychopath? When in reality the uke wanted to die and jumped off the staircase hence lost his memories and the seme is trying to protect him at all cost? There were multiple servants and a girl one that the seme thought it would be best for the uke to be with and live a normal life. It’s a very confusing one . Also the seme was blond and the uke had black hair and is super rich. If anybody knows the title I would appreciate it
