Won't something interesting happen? Although Tomoko complains in her heart, she doesn't really do anything herself, but spends her lazy middle school life with Xiaoyu and the gang that suddenly breaks in (at least that's what she thinks). One day, Tomoko sneaks into the roof of the restricted area with the key she found. While enjoying a strange sense of freedom, a junior student I didn't know snuck up onto the roof. Tomoko is very flustered and begins to behave strangely.
