There's no rape in this she clearly consented to everything at all times, honestly the flow of the story made no sense, we have a saint male mc, a female mc who makes extremely out of nowhere bad decisions, a third wheel friend who just exists to tell the male mc to confess to the female mc, and finaly a love interest for the female mc who honestly made the least sense out of anyone, no motives, no nothing aside from he looks evil(in "some" scenes) and apparently has the baseball team shadowing him whenever he has sex letting them have sex with his girlfriend("with" her consent of course) a few times(two, the second time mc shows up and beats everyone up apparently).
The story suddenly cuts off at a good point and turns into a horribly written shounen manga, it had great potential to turn into many types of good stories(from tragedies to happy endings) but no... after the girl get's tossed in the water tank everything goes downhill...
If you read this thanks
