I am looking for a yaoi/shounenai manga that is idk if wch is wch cause they both have the potential to be uke/seme but one is i think brown/blond hair and the other is black haired. I remember they are a bit bitter to each other cause both of them are popular. I think the black hair is in a sports club, ant the brown hair is a student council member. I forgot the title of it. They are always bickering when they see each other.
