Please Help me find this bl

Okay so I have read this long back I don't remember the name but only some bits and gists from the story. It is a university bl, short one only few chapters. There are Two guys one is gay and the another one is straight so the straight one is an athlete as much as I remember. So there are these scenes I remember from it.
S1: Both of them went for car ride ,they stopped in the bridge it's Sunset time ,tye straight one confess his feelings to the other one , and they make up.

So basically the straight guy is same like any other , he and the ML they kiss since then he went crazy about it. He kept having girlfriend until he realizes his feelings for the ML

Another scene it's weird but after their fight they make put but in that process while doing it the straight guy wears his ex 'girlfriend 's lingerie (he was wearing that while doing the deed) it was the same his ex left at his house back then. So if someone have read it please let me find it I want to add this on the list
