Miho Kohinata & Kyoko Igarashi(THE IDOLM@STER CINDERELLA GIRLS)

When you were a student, did you deliberately have the guy touch the boy's chest or show the girl's pants in order to get the boy in the class to stick to your friend's girl?
I was humiliated, but on the contrary, I think that the liking of each other will increase considerably.

Then, when deciding on some kind of group, they are forced to come together and get naughty in the flow.
It's common.
