第 4 集: 雪乃提出學校贊助的商場校外教學，儘管社團規則限制校外活動。

4

Yuki is practically bouncing off the walls after coming up with an idea to take a field trip outside the school grounds. Rii-san and Kurumi remind her that club members aren't supposed to leave the grounds, but Yuki's convinced that if it's a school-sponsored activity they won't be breaking the rules. Their destination: the mall! Take a stroll down memory lane, to the days before the group first met Mii-kun. (Source: Crunchyroll)
