Janu visits Hana in his office on Christmas evening, where Hana has gained entry and prepared a private encounter. Their conversation shifts from mocking the holiday to Hana boasting about her skills in picking locks, which she used to bypass Janu's office door. Hana expresses a desire to compete with another student, Tora, for Janu's attention, framing their sexual encounter as her way of claiming a "prize."
Hana begins to stimulate Janu, but he interrupts to request oral sex. Hana attempts a blowjob but struggles due to the size of Janu's member, leading them to shift to a "Plan B" where Hana positions herself on Janu’s lap to engage in intercourse. During the act, Hana questions Janu about Tora's knowledge of their relationship and expresses her fantasy of forcing Tora to watch them together. As they reach a climax, Hana begs for affirmation that Janu prefers her over Tora. Afterward, Hana expresses a desire to have sex on Janu's desk in the future. The event concludes with Hana tidying the office, while Janu reflects on Hana’s manipulative nature and her obvious insecurities, fearing the potential complications of her obsession with Tora.
