My wife, Yui, is a neat and beautiful wife. One day, a man named Isobe, who is said to be his wife's former homeroom teacher, comes to the house. He was a man with a vague aura, so he left early... A few days later, I found Isobe's smartphone stuck in the gap of the sofa. I should have cleaned this place yesterday... Does that mean Isobe came to my house again between yesterday and now? What are you doing? Even though I have a bad feeling about it, I look into the contents of my smartphone to find out the truth.
