After six years of marriage, the innocent Saki has devotedly supported her husband Kousuke. Seeing her husband struggling day in and day out to raise funds for his company, which has fallen into the red due to the effects of the coronavirus, Saki suggests that she apply for assistance from her estranged landowner and father-in-law of the Kanematsu family.

Katsuharu, the father-in-law who welcomed him, readily agreed to provide financial support.
