I moved to Tokyo for work three years ago, but I was too busy to go back home for New Year's, so it's been a year since I've been back home and seen my mother. I was starting to miss my mother's cooking, so I took advantage of my summer vacation to go back home, but this summer, the weather was abnormal and it was hot every day. Living in my parents' house without air conditioning, I couldn't stop sweating from morning to night. And maybe because of the heat, I was distracted by the sweat running down my mother's neck, dripping from her forehead, and floating on her chest.
