Looking for a BL title

I used to read a REAALLLLLYY good BL manga. There's a handsome-kun character which hates the male lead, the black-haired male lead has long bangs and is very shy. And fron what I remember, it rarely updates. Anyone knows the title? Also, the male lead is very rich so they went on a vacation in one of his rest houses at some point. There was a scene where the handsome-kun helps the male lead vomit lmao and it was really erotic
