Suddenly So Close in the Darkroom! Kinda Dangerous Club Activities?! - Passionate School Festival! I, Yamada, Will Be the School's Queen!
When Yamada learns of Kosuda's membership in the photography club, and finds out that he is going to develop a few pictures in the dark room, she turns that into a sneaky scheme to "obtain his golden cherry." There, as Yamada accidentally trips the plug to the red dark room lights, Kosuda accidentally touches her bare breasts, but has no idea what he was touching. Disappointed, Yamada runs out of the room after Kosuda finds the switch to the normal room lights, but he catches up with her in his bicycle and offers her a ride home.

Yamada's First Time: B Gata H Kei
Yamada, first name withheld, is a 15-year-old girl who has just entered Takizawa High School. Easily considered exceptionally beautiful, she has only one problem with her own body, she thinks her vagina looks weird and is very self-conscious about it.
Upon entering high school, her dream was to have casual sex with 100 men but therein lies the problem, she believes an experienced partner will tease her about the way her vagina looks or simply the fact that she's a virgin. She stumbles upon the solution in the form of Kosuda Takashi, a fellow virgin, whom she believes will help ease the transition to more experienced partners.
There's only one small problem, Yamada doesn't know anything about sex or the ancient art of seduction, meaning her quest to conquer Kosuda will be a difficult one.
