Ichika, who loves taking care of people and wants to do a job that pleases people, will be dispatched to the Ashida family for two days and one night as a part-time job for a housekeeping service. Her client, Mr. and Mrs. Ashida, are away from home. The Ashida brothers, who are withdrawn and are in the middle of puberty, use their son's position to play with Ichika's body like a game... "At first, I thought it was a trivial prank, but..." Ichika pulls back. A series of fornication called mischief that escalates by a shut-in boy and falls into acme hell.
