Class de 1-ban no Boss Gal wa Boku no Mae dake Kawaii Ecchi na Osananajimi

"Want me to give you a hand at masturbating?" Naokage Morita and Ayano Kirinoin who attend the same high school have been childhood friends for a long time, but since entering high school they've gotten more distant. Ayano is the most beautiful girl in class, and with her constantly expressionless face had become something like a leader taking charge of the class; Naokage on the other hand, with his quiet personality and plain appearance spent his days silently in high school. 'Back in middle school she was closer to me; she was a girl who cried, laughed and had all sorts of expressions. I wonder if something happened...' Naokage worried about Ayano who had become something like a boss gal, and it was then that an incident happened. (Source: BookLive, translated)
