Ao Sudo is a self-confessed otaku. He talks about otaku stuff with his classmates every day and of course he never had a girlfriend. Perhaps because he is seen like this, his classmate Umi Tono calls him Otaku-kun instead of his name and treats him coldly. But he also had a dream. His goal is to find a good partner and start a family. The school also has a club to make dreams come true, a child-making and pregnancy club. The child-making and pregnancy club is a nationally sanctioned club activity that encourages students to become pregnant and conducts pregnancy activities. Ao was able to join the club after the selection process. According to his advisor, there is a girl who wants to be Ao's partner. Ao couldn't believe his eyes because the girl who entered the club room was Umi Tono, who treated Ao coldly.
