There is some partial nudity in the intro credits although it doesn't show any nipple, there is cleavage of two girls, one has larger breasts and another is a males chest. It almost looks like they have skin colored outfits on.
A girl forces herself on a boy and french kisses him aggressively. Although no tongue is seen, the boy emphasizes her tongue is in his mouth.
There is significant fan service, especially in the opener. Naoto is kissed several times, without consent, some of them are forceful. Romantic feelings, sexual innuendo, and non-graphic nudity muddle through this show's convoluted love story. Naoto and one of the girls end up living together while they are still in high school.
A couple of storylines center around teenage pregnancy.
