Not in college setting but it is very interesting, try “rainbow city”
Also try “little mushroom”
“Into the thrill”
“Monochrome rumor”
Very interesting but it’s not completed

"Serious Joke"
High school setting but completed. Loved how they addressed trauma, and how characters do make mistakes and take enough time for the character development
Any interesting bl MANHWAS? + if it's in a college setting, completed(if it's ongoing thrn i hope it has a lot of chapters), and not THAT toxic
