Switched into another body

Hey y’all. I need help finding a bl manhwa. Basically this guy was an assassin or something, he got betrayed by his friends and was killed and reincarnated in the body of this slutty actor who had piercings on his ass. He helped this little kid from being kidnapped and no let the kid is a big shot in the industry and knows that he’s in the actors body now. Please help, thanks
