I love my father-in-law more than my husband...

Her husband, Koji, and his wife, Yuka, come to their parents' house to take care of their father-in-law, Jo, who has fallen ill. Her husband returns to work, and Yuka is left behind as she takes care of the patient, hiding her feelings. Yuka still loves her deceased wife and has feelings for her father-in-law, who works single-mindedly. Not as a father-in-law, but as a man... At that time, Yuka receives a phone call from her husband's cheating partner saying, ``I want you to break up with me.'' She can no longer suppress her feelings for her father-in-law, and runs away from home with her emotions...
