it was a love triangle im pretty sure, and also a bl and it was college styled, one of the ml's had black hair and was catholic, the other ml i cant remember much abt him lol but im pretty sure he didnt like the catholic one and the mc is smaller with brown hair and kinda mean to one specific person in their class and hes very nice i think he doesnt like him because he thinks the one of the ml likes him, i was reading this on bato but ive ovb lost the name
