Ichiro Kuga is a manga artist struggling to support his two young siblings, and he's in need of an assistant. Shiori Goshiki wishes to become that assistant, but her background is unusual in more ways than one.

Ichiro learns the hard way some of the physical implications of his newfound bond with Shiori. Now that she has a permanent place to live, it's time for the two of them to do some shopping.

Rainy weather complicates plans for Shiori and the Kugas. When Machi and Fumio are down in the dumps as a result, Ichiro and Shiori get creative in their efforts to make the most of the day's disappointing weather.

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.

With the pact no longer hanging over them, Shiori and Ichiro are free to live and love on their own terms. But that doesn't necessarily mean there are no complications left to address.
