"I'm home, mom" Kazuya returned to her parents' house where her mother, Yuka, was for the first time in a year. Yuka was thrilled to see her beloved son, who had been raised by hand. Two people who loved each other every day a year ago. Yuka can't control her excitement when Kazuya grows up as a full-fledged man as a member of society. We urge each other to fill the gap of the year, but it is not enough. The gasping voice turns into a scream at the pursuit piston that does not end so much that it seems to be eternal.
