My wife is the type of person who can't cheat. Everyone on the morning commuter train sways along, looking grumpy yet with dead fish eyes. Tired of the bleak interior, I glance at the advertisement hanging from the ceiling, and a certain topic catches my eye. "20% of full-time housewives are sexually interested in male daytime visitors!" Written in obscenely thick Gothic font, this sentence somehow intrigued me. My wife, who has a laid-back and gentle personality, is often praised for her beauty, and when she wears tight-fitting clothes, her figure is so good I don't know where to look. However, it seems she has no interest in any other man besides me. "I'm devoted to you," she says with a smile, and when I see her say this, I truly feel glad that I married her. It seems my wife is the type of person who can't cheat or lie at all. But for some reason, her cell phone is always locked.
