Janu spends a Friday afternoon at a karaoke venue after being persuaded by Dayai, Tora, and Tuli. The atmosphere is filled with typical banter between the students, including Tora’s energetic hosting and playful friction between Tora and Dayai. Janu observes the group and shares an awkward moment regarding a recent, intimate interaction with Mori.
As the rest of the class arrives, the booth becomes crowded, leading to various social interactions, including Sora’s overly enthusiastic greetings and Nirima’s teasing. Nokana is reluctantly brought along by Kio and Eruka, eventually agreeing to sing. Roni makes a brief appearance but leaves after grabbing snacks, having no interest in the singing. The evening concludes with the arrival of Zena and Oki, who discuss the latter's garden. Janu spends the time enjoying free food and observing his students, deciding to refrain from singing himself but promising to participate more fully next time.
