[DeepL Translation - needs review] Volume 1: The junior who is one level below me is big in many ways! For some reason, Yuu Ogata, a member of the library board, is being missed, petted, and cared for by a strange junior student, Mr. Omori! The natural Omori-san is always trying to get in the way, and today's slapstick routine is about to get underway!
