20. An unprecedented game

For example, the principal is a maid, and the strange classmate next door, I really want to tell you that the main line is a campus romance between a man and a woman or several couples of men and women, which doesn't seem to meet your requirements, so I didn't write it. You can contact me in private if you want ~

I specially wrote something that was not in the other answers. Very nice! Hope to adopt ~

Ps: I have some film here. If you want, you can come to me and I'll send them to you ~
