CAWD-960 A four-member JK (high school girl) co-ed school club at the Metropolitan Municipal School, deviating from school rules and regulations. Karin-chan, Akisa-chan, Yuna-chan, and Itsuki-chan.

Four childhood friends, who went to the same school together, spent their school days together, ate lunch together, and walked home together. They were inseparable, always thinking they would remain best friends. One day, the cheerful and lively Meisha kissed their teacher… Itsuki and Karin, who witnessed it, were shocked. The next day, when they questioned her about it… “Actually, I like him too…” Itsuki whispered. “Me too!” “Eh, me too!” Unexpectedly, all four of them liked the same teacher. A middle-aged teacher… that’s okay. Breaking school rules, even breaking the law… that’s okay. Societal views didn’t matter. Teenage crushes are utterly irrational, filled only with passion. When anxious Yuna wanted to possess him, Itsuki and Karin said they couldn’t let him go this time. The three fought over the teacher, turning into a harem. Meisha watched from afar… The next day, they also called the teacher over, and their first argument ensued. To decide who liked the teacher the most, a ruthless battle for sex began. Who will be chosen…?
