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.

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'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.
