Kanon with a determined heart (Pixiv Fanbox)

There is a summary zip at the bottom of the page.

This is Kanon Matsubara from BanG Dream!.

Kanon had inadvertently entered a men's bath.

She was the only one in the bath, so she didn't realize it was a men's bath.

The boys came in and she took shelter behind a rock before they spotted her.

That's the way it's set up.
