Chapter 4: Not A Chapter

So I'm thinking of writing a Romance Novel (Not Yuri). It'll be based on the world of Haikyuu, but the MC won't probably play volleyball. I just wanted it to take place there so yeah...and should it be classified into a Fanfic or Novel? The MC will be an original character and Kenma will be the love interest. R-18 also 🤭 Suggest a name.
