It's been three years since I came to Tokyo to get a job, and I couldn't go home because I was too busy on New Year's Day, so it's been a year since I came back to my hometown and met my mother. I missed my mother's taste soon, so I went home using the summer vacation ... This summer, it seemed to be abnormal weather and hot days continued every day. Living in my parents' house without air conditioner, I couldn't stop sweating from morning till night. And maybe because of the heat, I was fascinated by the sweat flowing from my mother's nape, the sweat dripping from my forehead, and the sweat floating on my chest.
