So I forgot the title of thi bl manhwa I read a year ago. It was in black and white. Protagonist is a bodyguard and friend with the young master from some rich powerful cult like family. They've been friends from childhood but their relationship turned hostile for some reason... at the start of the series the two had tension but still the rich guy friend reached out to protagonist and invited him to his birthday. Rich guy then tasks protagonist to investigate who is putting him to sleep and getting this tattoo done on his back.. AHH that's all I remember. Please help me find the title. （/TДT)/
