It's been a few years since I moved to Tokyo to find a job...I work for a black company where I can't take a day off.Her mother kindly welcomed me, who was physically and mentally exhausted.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 captivated by the sweat running down my mother's neck, the sweat dripping from her forehead, and the sweat floating on her chest...
