Unless you're like the dad or sole caretaker you shouldn't be showering with a young girl anyway to avoid any potential problems. It's not about guilt.Not a bad chapter, but the author made the MC react way too much to a child, his embarassment means he didn't see her just as a kid.
Of course we know he is not a criminal but damn, that kind of reaction would make me guilty him on the spot.
I know I wouldn't.
