1, 3-5, 7-8: Onnanoko ni Natte
Takumi suffers from a terminal illness, agrees to try an experimental gene therapy and is changed into a girl. She lets her old friends talk her into allowing them to feel her up, gets invited to clothes shopping with Sogahara Anri, the Miss Perfect from another class and brags to her friends afterwards, teasing them with their virgin status that they will never get a girl in their lives, and how as a girl being a virgin is a good thing. They talk her into letting them practice on her, first confession of love and it escalates from there. Her oldest friend Ryou eventually breaks things up and brings her home. Apparently he has some sort of breakdown over how she is such a slut when the Takumi he knew was a “proper man” and only interested in girls and … I want to say things stop to make sense completely, but it’s not like anything made any sense up to that point. Apparently he is so angry with her for being such a slut and enjoying him raping her so much (and she does) that he chokes her, all the while crying over his friend Takumi.
