Araburu Kisetsu no Otome-domo yo.

Izumi Norimoto and Kazusa Onodera used to giggle and play together as kids and were like siblings. However, as they developed into middle schoolers, Kazusa started to perceive him differently, and sadly for her, so did the other females. As a result of being ostracized, Kazusa was forced to keep her distance from him as she entered high school. But after she joins the literature club, she makes pals who keep her busy. The club's notoriety at the school for reading out loud sex scenes from literature novels has prevented all professors from agreeing to serve as its adviser. One of the females mentions sex while they are talking about items they would put on their bucket list. The five girls are affected by this one word, which causes sex-related thoughts to start dominating their daily thoughts. As a result of interrupting Izumi during a very private time, Kazusa is forced to confront her genuine feelings for him and is thrown into a state of emotional chaos. The five girls must work incredibly hard to maintain both their sanity and their club now that their hearts are racing and the book club is in danger of being immediately disbanded.
