Looking for manhwa

Hi so im looking for this particular bl. Its a korean bl. It used to be like on top one. The storyline kinda whack but i cant get it out of mind for some reason. Its abt a waiter at a bar who encountered this seme who is like a gangster? Like someone who is rich or maybe a loan shark? Im not exactly sure its been like years. And the seme and uke got down and dirty… i know this seems like the plot to almost every manhwa ever but what i remember is the distinct artsyle and the seme is kinda like a red flag. Very aggressive in bed… can someone please help me, ive search the vortex of this site and still cant find it
