In the comic ai think uke plays double character like as an assistant/employee at seme working company .....he is also a singer at bar ig......one day seme starts getting attracted to the singer non other than his assistant himself and also I think uk and seme has some previous history.

By the way ig i read this comic in webcomic

This manga is about how two sons parents marry and immediately the sons hit it off. I think the older son is gay and the younger son soon quickly falls for the other son. But years pass and nothing happens until the younger one comes into the older one. Of course there is a misunderstanding about feelings but then it gets resolved. They both liked each other after first meeting.

basically I watched it being on YouTube. I remember it had a ml which had tan skin golden eyes and black hair he was either a prince or a king I can't remember. and the fl was either a male or a female and they had something that made them extremely attractive something like a butterfly but at the same time dangerous. the ml's mother was the same that's why he doesn't like them at the start. That everything I know, if you know the name I would really appreciate it!
