Ep. 21: Sakurai organizes a Christmas event requiring couples and gift exchanges.

21

During the holiday season, Sakurai arranges a Student Council activity where participants must pair up as one male and one female for a random gift exchange. Several boys compete for Sayuri's attention, prompting Ayame to tease her about selecting Riku, a claim she rejects. To disrupt the proceedings, Ayame unexpectedly claims Riku as her partner, surprising the group and upsetting Tsukasa and Mina. Meanwhile, Sayuri secretly selects a present for Riku, while Tsukasa and Mina eagerly choose gifts for him as well. The event highlights the complex romantic dynamics and competitive feelings among the students as they navigate the holiday traditions and interpersonal relationships.
