Janu encounters Oki in the school hallways while she is struggling to carry several heavy boxes. After Janu assists her by taking some of the weight, they proceed to the library, where they find Nokana. The three engage in a conversation about their social circles and the dynamics of their respective friendships.
Janu, observing the two shy students revising biology, decides to intervene by providing them with a highly detailed, somewhat explicit anatomy textbook. He insists that this is an educational requirement of his teaching methods. Despite Nokana’s hesitation and Oki's embarrassment, the two girls begin to study the material, leading to a series of awkward revelations about human anatomy. Janu encourages them to continue this self-study, and the event concludes with the two girls departing in a flustered state, while Janu reflects on his success at playing the role of a teacher.
