I am currently a high school student living in Tokyo. Feeling that life is too meaningless, I dropped out and returned to my hometown to live at my aunt Megumi's house. Here, I reunited with Akemi, my cousin. We were very close as children, but since moving to the city, we haven't seen each other. Because it’s been a long time since we last met, both of us felt awkward talking to each other. Suddenly, she asked me if I had a girlfriend. She teased me about my foreskin not being retracted yet. That touched my pride, and I decided to prove it to her. However, I have strong feelings for her; I know she is not happy with her husband, but she chose him. And after she leaves, everything here will just be the past; we will always just be relatives, friends...
