Shiori and the Kugas finally make it to the zoo, and it's Shiori's first time visiting one. It's also her first date with Ichiro since they officially became a couple, and there are unexpected hurdles to clear.

It's time for the Christmas party, an annual tradition at Hiiragi Apartments. Shiori continues to grow closer to Ichiro, but she also spends time with some of the other friends she's made since her arrival.

Shiori's parents track her down and confront her in person about her situation, which she and Ichiro now must find a way to explain. Can they convince them to let her stay, and is there any way to annul the Engagement Pact?
