Mitsuo always cares not only for Megumi, but also for pensioner Masutaka and job-hunting Koji, and is an absolute presence in the Yuki family. One day, Mitsuo disappears. No matter how long they waited, the good news did not arrive, and the Yuki family became dark as if the sun had disappeared. Masutaka's dejection is particularly severe, and Eka cannot bear to see such a situation, and she vows to protect this house until her husband returns.
