Any yaoi about an erotic novelist x his model?

I didn't know what u ment by model(￣∇￣") but this is about a novelist who bumps into a student and the student hurts the novelists arm so the student has to work for him in order for the novelist to forgive him

I know the description is bad but in rubbish at English I know the story isn't on manga go I couldn't find it on here T-T but I hope you like it if you do read it

Sorry but following ╮(￣▽￣)╭

the other guy is not his model as far as I remember, but it is about an erotic Novelist.

Sorry for not being detailed but things like this is what I'm looking for:
