"Female trainer provides thorough guidance! Fascinated by those words, I went to a personal gym in Tokyo with my wife. The trainer was named Rio, and she was kind enough to guide us, but I was stunned by the strangely close distance. And Rio suggested a one-on-one lesson to me when my wife went to take a shower. A few days later, I told myself that it was okay because I was just going to train, and I headed to the personal gym where Rio was waiting.
