One day, when summer was about to end, we were planning to have dinner with my wife's family. Sister-in-law Mizuho was beautiful and stylish. And while my wife went to pick up her mother-in-law, I was alone with Mr. Mizuho. Mizuho-san gave me a beer because I was worried, but at that moment, a large-scale power outage occurred. By an unexpected accident, I spent the night with Mr. Mizuho, but I was afraid of the dark and couldn't control my reason because Mr. Mizuho wouldn't leave me.
