Man, this is such a *light-hearted* take on this prompt that I wonder if Nacchan either understands what he's doing, or he knows and doesn't care. Because spying on people having sex is drastically different than getting footage of practice, even if that's also pretty shady.

And he's going to use it as blackmail for passes. NACCHAN THATS BAD???? I kind of want Mizuki and Indou's reaction too - I'm sure it'd be veeeery different.
