Manabu, a ronin who lived in his parents' house, was crazy about the search-type monster collection game that was recently popular in the world and wandered around the neighborhood.One day, Manabu, who was led by the game and came to an empty house where people rarely entered, noticed that he heard a woman's voice from the back room.And when I timidly looked into it, there was Yuka, a married woman who her parents were familiar with on a daily basis, writhing in an indecent appearance that can not be imagined from her usual quiet and neat appearance.
