......ngl I did tear up a bit once I found it.....I had just looked for like an hr browsing all sorts of lists...so many mixed emotions I cant even call it relief lolll
IT WAS IN MY ALREADY READ LIST TOO usually thats the first thing I check but since I lost almost everything and only started to fix it a few days ago I didnt check....I'm sosososo glad I was like let me check just in case when I saw the cover

Okay so college bl
Best friends to lovers
Both are well built and very popular with girls but one is stoic/dark hair and the other more carefree/playboy/straight type
Dark hair has an unrequited crush on him
Playboy has a girl over and the stoic one is about to leave and she's like "can't you both stay?" playboy doesn't mind and stoic guy is like fuck it whatever
And then it ends up in a sandwich with playboy on bottom girl in the middle stoic on top
Top guy mentally pretends he's fucking his bsf, staring at him, and I think? He holds hands with him or (almost?)kisses him and then after that playboy is like why was he doing that and starts to overthink
...thats all I got....
Please answer my prayers lol
