Recently, my wife, who is picky about dieting, seems to be addicted to a certain video. Lose weight in 10 minutes! The female trainer in the video is Hibiki, who runs a personal gym in Tokyo. A few days later, I went to Hibiki Gym with my wife for a free trial. Hibiki taught me the training in a friendly and polite manner, but for some reason the distance was strangely close. And I was invited to take a lesson alone with a voice that my wife could not hear.
