Page 11 seems a little strange, with Shiori mentioning gymnastics management. The other translation has her talking about becoming the track manager, and that makes more sense. Is that perhaps what the translation is supposed to be?
This is how NTR always happens in manga. "I don't want other people to know that they took a picture of my breasts". Ntr always happens to these woman because of this reason. They refrain from reporting to the police because they don't want people to know what happened to them. They agree to do whatever the bustard wants because he threatens them with realising a picture or video they have of them. To my eyes it'd stupid to be honest. To think that they'd prefer to be raped forever than reporting it. If they report without him knowing, police could get to his phone before he can upload the dirt he has on the woman. It always pisses me off. And now shiori is doing the same thing.
It's not like they got a picture of her bare tits. No one would say anything about that picture
