My grandpa used his retirement money to buy a new house, so I came to celebrate the new house, leaving my busy parents behind. I was Kokoro by the beautiful exterior and tried to open the front door, but the door wouldn't open! I had no choice but to go around to the back door, and this time the door came off... I had a really bad feeling, and it turned out to be true! After that, one problem after another occurred in the house, and my stressed aunts attacked me to vent their frustration and eternal frustration...sweat.
