help me find this manhwa pliss

i can't seem to remember this manhwa's name. but what i remembered is that the mc has dark hair, working as a server at a club?? like those private karaoke rooms. and suddenly this one omega daddy was searching for him cuz his son can only be stable by the mc?? and the son's name is ahro or something (blonde hair, kinda like chase) and he was rude af. and the cause is because they were half-marked with each other or smthing
