Could it be this one? https://www.mangago.me/read-manga/double_trap/
Sadly no :(
was it popular at one point? like an omegaverse?
I'd say it was decently popular?? I've remembered an extra detail that the main couple's top had black hair and wore glasses??
Oh yeah it took place in a college and it wasn't an omegverse!
OK so it's this manhwa in color that has a main couple and a side couple but the main couple's bottom has red hair and is really insufferable while the second couple's bottom HAD a crush on the red hair guy but also had beef with his top? The top had lighter colored hair. That's lowkey all i remember PLEASE help me find it I loved that side couple a lot more than the main
