Help

I’m looking for a BL that I read a year ago, but I can’t remember the title. It was a completed, relatively short series that took place at a college or university.
The top had blond hair, was rich, popular, muscular, and lived in a large house or mansion. The bottom had black hair, was also muscular, and at the beginning of the story, his girlfriend breaks up with him.
The two main characters aren’t friends and are more like rivals. At some point, the blond guy throws a party at his house. The black-haired guy isn’t invited, but he shows up anyway. They accidentally end up falling into the pool, and afterward they go to the blond guy’s bedroom. After that, they begin a friends with benefits relationship.
I’d really appreciate any help finding this BL. Thanks in advance :)
