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.

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.

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?
