High school students Yuma Okazaki and Hotaru Mizushina are childhood friends. With their respective boyfriends, Takeda and Fujiwara, their lives couldnt be more perfect. From playing in school to going on group dates, it seems nothing can break their bond. However, during one such group date, Hotaru makes an unexpected move. While Takeda and Fujiwara are distracted, she begins stroking Yumas thighs. Taken aback by this peculiar action, Yuma awkwardly retreats to the toilets, followed shortly by her aggressor. Now in private, Hotaru forces the innocent Yuma into a locked cubicle and whispers into her ear: "Youll be more nervous with a boy; Ill help you practice."Edited by stinghyFinal Edit (Writer/Coordinator)High school students Yuma Okazaki and Hotaru Mizushina are childhood friends.
