So the mc is like a struggling author who jast written like good and/or popular books. One day he like meets a cat and sees like a poem and a laptop. These things are possessed by an old author who was really good at his work. I remember he has like this rival dude who hates him because he's dating this girl who went to college with both of them and the rival liked her. In the end I believe he becomes good by himself.
Bro even the official chapters are about reach 30. Like when are they going to update it so annoying
