I don't know their names so I'll give them replacement names, not to confuse anyone...
Joe likes John, the popular boy in school. Joe has a nerd friend named Jesse who secretly liked him for a while but never told him. Joe starts to have dreams about his friend and goes, "WTF?!"
Joe finds out that John is sleeping with his science teacher. John starts to like Joe after Joe finds out.
Then something else goes on then John gets a hair cut...

Does anyone know the title of this story?
