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.

Shiori and Ichiro explore the ins and outs of how daily life will function under the terms of their Engagement Pact. Ichiro's friend and mentor Momoka comes over for a visit, but this has an unexpected effect on Shiori's state of mind.

Shiori goes with the Kugas to visit their father's grave, as her relationship with Ichiro slowly deepens. When she comes down with a fever, it becomes Ichiro's turn to help her get back on her feet again.

Some amazing New Year's luck sees Shiori and the Kugas take a trip to a hot spring resort. But Shiori's mother Miyako is growing impatient, and she begins taking steps to get her daughter to return to the island.

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?

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.
