My daughter, Kanoko, got married, and we remodeled the house into a two-story house. Not only I, but my wife, Ruka, was also happy that my precious only daughter had returned.

Since then, Ruka has been increasing the opportunities to visit my daughter's house with all sorts of unnatural excuses. Lying with lies that are obviously lies...
