Part 6

Risako visits a lava field with Aio but cancels on a date with Sota. After a beer factory tour, Sota asks Maya on another date, but she refuses.

Sota comes to a decision and informs the other housemates. Aio reneges on his invitation to Risako so he can ask Yui on a date to a soccer match.

Masao learns that he snores and Aio and Yui go fishing. The night before Maya's college fashion show, Yui and Risako talk to her about her behavior.

With his feelings growing for Risako, Masao decides to make lunch for her. Kaito and Maya go ice skating, then spend more time together that night.

While out to a bar together, Aio tells Yui his feelings. While Risako is away for work, Maya and Yui discuss their thoughts on her behavior.

Masao tries to comfort Risako, who’s still at odds with the girls. Later, Aio tells Risako the truth about his relationship with Yui.

Risako makes it clear that she knows how far Yui went with Aio. After going on a glassblowing date, Masao tells Risako his feelings.

Masao asks Risako to give him her response at his band's Christmas concert in Fukuoka, but first she talks to his notorious bandmate, Enon Kawatani.

As previous members celebrate the holidays, Yui's birthday approaches in Karuizawa. Meanwhile, Risako travels to Fukuoka for Masao's show.
