It's been three years since I moved to Tokyo to find a job, but I was too busy to go back home for New Year's, so it's been a year since I've been back to my hometown or seen my mother. I was starting to miss the taste of my girlfriend's mother, so I used the summer vacation to go back to my hometown...but this summer, the weather seemed to be abnormal, and the days were hot every day. Living in my parents' house without air conditioning, I couldn't stop sweating from morning until night. And is it because of the heat that I feel uneasy?
