All the girls here are wholesome except the bunny girl childhood friend. She acts like a pure maiden claiming she still and has always liked the MC, yet she sleeps around once she got into college(highly implied by the author from the way the scene is drawn and her reactions, you can tell she's not a virgin since the author always draws blood in almost all of his doujin during first penetrative sex except for P5 Yoshizawa doujin since she does gymnastics). I can never understand this type of character in hentai where the heroine has always liked the MC for a long time yet sleeps around anyway.
