Your five pairings are...

Generator Settings

Yuri Pairings Only (if you're writing smut)
Include Canon Pairings (Hisao and ...)
Include extra characters (Miki, Suzu, Class 3-3, etc.)

Okay, but now what do I do?

After you've generated your five pairings, choose one or more and write a story about it.
It doesn't have to be any specific length or genre, just write a short story about one of the randomly chosen pairings.
