It's been three years since I moved to Tokyo to become a musician.My girlfriend's mother kindly welcomed me without asking anything when I was exhausted both physically and mentally because I could not make her dream come true.Even so, this summer was hot, and living in my parents' house without an air conditioner, I couldn't stop sweating from morning to night.Then, maybe because I was confused by the heat, I was fascinated by the sweat running down my mother's neck and the sweat floating on her chest.
