Hey I’m looking for the manhwa I’ve read: it’s a Yaoi about a black haired guy that writes a novel secretly and uses someone from the same Uni as a character reference, and that guy is blond and used to be an ass but they end up together at some point

Does anybody have recs for mc‘s like Cha Euijae from „The hunter wants to live quietly?“ (preferably w/ the same kind of ml but whatevs) thank uu
