I have been reading this story since I was like 15 now I am 18 and I feel like we lost the plot… im gonna have kids before I see the ending

Pls help me everyone! I’m trying to find a BL story I read a while ago, but I can’t remember the title. Here’s what I recall:
•One of the main characters is kind of antisocial, a bit of a delinquent.
•The other MC is more of a regular guy, nothing too special.
•The “normal” MC is assigned to supervise the library by his teacher.
•The delinquent MC starts showing up every day to read books, and over time, they begin talking.
•There’s a scene where the delinquent suddenly shows up at school looking disheveled and out of place.

That’s all I remember! If this sounds familiar to anyone, please let me know the title. Thanks!

Includes seme that are playboys, cheat, take the Uke for granted, treat the uke as only a friend with benefits or shows limited affection toward uke. This also includes seme that think the uke will always be by their side until they’re not or doesn't see uke as a love interest. Overall, angsty stories.

Also, some of these ML are actually not that bad but if our MC is being treated poorly then I’ll add it.
