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 called Hibiki, and she seems to be opening a personal gym in Tokyo. A few days later, I will go to Hibiki's gym with my wife for a free trial. Hibiki taught her training politely, but she was strangely close to her for some reason. And she was invited to take a lesson alone with a voice that her wife could not hear.
