helppp

that one shounen ai (?) manga that was about a writer x fan. they're both in highschool, and actually in the same class but writer's been absent for a while for some reason. they meet on the train, while the fan is reading the writer's book and he starts to read it with him, i think the writer insults his book as well? but fan defends it. uhh the writer was blond, but dyed his hair black once he went back to school. that's all i remember lol. (also recommendations on anything about writing would be nice)
