At the start of the week, Aisha, Rina, and Odessa have a candid discussion about their physical insecurities and their impressions of their classmates. The conversation shifts toward their teacher, Janu, whom they generally admire despite his unconventional and casual teaching style.
The scene moves to the swimming pool, where Janu encounters Megumi. She continues her "radical scientist" persona, claiming she is conducting experiments, though Janu remains skeptical of her previous love potion schemes and dismisses her claims of having a harem. Fareeda then arrives, and Janu and Fareeda enter a private negotiation. In exchange for Janu’s support in the upcoming class representative election, Fareeda provides him with intel regarding a secret bet between Yuka and Megumi.
Fareeda recounts a conversation she overheard in the showers between Yuka and Rei. Yuka has made a bet with Megumi to see who can kiss Janu first and intends to leverage her growing rapport with him to win. Yuka also reveals she is aware Janu has an "Eruka" in his life but believes the relationship is non-existent or fragile. Janu acknowledges the information, deciding to maintain his "dense" facade while carefully monitoring the situation. He concludes that managing the first-year students is proving to be a challenging and exhausting endeavor.
