[Mosaic removal] My wife, who is picky about dieting and has recently gained weight, was stretching after watching a video.The female trainer uploaded to the video posting site seems to be called Yuu, and she seems to be opening a personal gym in Tokyo.A few days after that, I went to try Yuu's personal gym with her wife.She was kind to me during training, but she was strangely close to me only when I was there.And I was invited to take a one-on-one lesson in a low voice that my wife couldn't hear.
