Synopsis：Shuto Aoi is widely recognized as an otaku. Every day, he talks about otaku topics with his classmates, and naturally, he has never had a girlfriend. Perhaps because of this, his classmate Tono Umi is not called by her name but is referred to as an otaku, and she takes a cold attitude toward him. But even he has a dream: to find a good partner and start a family. Moreover, the academy has a club activity to realize this dream—the Pregnancy Preparation Club, which focuses on creating children. The Pregnancy Preparation Club is a nationally recognized extracurricular activity that encourages students to become pregnant and supports them through pregnancy. After a selection process, Aoi joins the club. According to the advisor, Aoi has a promising female partner. When Aoi enters the clubroom, he is shocked to see that the woman is Tono Umi, who has always treated him coldly.
