Umanohone Store and its characters are introduced. The Ero Hon G Men gives a speech on how she loves erotic books and how everyone loves erotic books. Sensei has to meet a deadline and has a breakdown over it.
Everyone at the shop gets a shelf where they present manga that they like in order to increase sales, which leads Hiotan on a quest. Later on, a Valentine's Day sale causes pressure, confusion, and nervousness.
Sensei needs help drawing a pantry shot in her manga and Umio helps her, causing comedy and embarrassment between the two. Later on, everyone enjoys a quiet rainy day at Umanohone.
Sensei has been sleeping at Umanohone (and not changing her clothes) to finish a manga by a deadline, but the staff at Umanohone is willing to help her out.
Hiotan caught a cold and took the day off from work, so Kantoku comes to her apartment and spends the day with her. Meanwhile, Umanohone has a Christmas sale.
