When I was reading this, I was waiting for the rape scene to happen. but when rape scene began, it wasn't really a rape scene. It was more of an okay scene.
There was a distinct lack of "okay" in that scene.
Nozomi never offered any form of consent, and all indications she gave and actions she took expressed the contrary: she didn't want to have sex. That didn't change before, during, or after the fact.
That's rape.
But rape isn't gentle. but I see it, I just haven't seen a girl rape another girl in a Manga before this one
Rape is unconsentual sex, it doesn't matter if it's gentle or it, she didn't want it, yet her "friend" made her do it anyway.
