Janu arrives at the school for a "detention" roleplay session orchestrated by Zena and Azula, who are dressed as disciplinarians. The situation quickly escalates into a sexual encounter, with Zena and Azula debating Janu’s recent romantic indiscretions, specifically his sexual history with them and Zena’s cousin, Hana.
During the event, Zena interrogates Janu about his feelings toward Hana, suggesting that he pursues her primarily due to a sense of obligation or fear rather than genuine affection. As the roleplay progresses, Zena reveals that she has been orchestrating this night for weeks, viewing Azula as a bridge to a more intense sexual dynamic. Zena admits to being a virgin and asks Janu to deflower her, expressing a desire to be submissive and "corrupted" by him.
The event concludes with Janu having sexual intercourse with Zena, during which she reflects on her desire for depravity and her willingness to be used for Janu’s pleasure. Janu ultimately decides to ejaculate on Zena’s back rather than inside her to avoid the risk of pregnancy. The session ends with Zena and Azula planning further sexual activities, leaving Janu feeling exhausted but acknowledging the addictive nature of their dynamic.
