Forgotten title

Hey guys so mangago deleted all the things I’ve read and bookmarked and I’m looking for a bl/yaoi manhwa I read months back.

The only thing I seem to remember is that the top and bottom were sex friends? I think the top was a blonde and the bottom had blue hair? The setting must of been a university and the last thing I remember what that they were going on a school trip to the beach? The bottom must of confessed there and got rejected.

They initially didn’t get along but became friends. I think the top had trauma with romance and wanted them to still be good friends but not have any romantic interest in each other? There was also this white haired guy that used to know one of the characters?? He was in the bus on the school trip with them and was interested in one of the MCs…..

This is such a vague description but I hope someone could lemme know what it’s called if they know…. The last detail is that it defo had 50+ chapters I think.

Thanks
