I am currently a high school student living in Tokyo. Feeling that life is too meaningless, I dropped out and went back to live at my aunt Megumi's house. Here, I met Akemi, my cousin. We were very close when we were young, but we haven't seen each other since moving to the city. Since it had been a long time, we were both shy talking to each other online. Suddenly, she asked me if I had a girlfriend yet. She joked about my foreskin not having dropped yet. That touched my pride, and I decided to prove it to her. However, my feelings for her are very strong; I know she is not happy with her husband, but she chose him. And after she leaves, everything here will just be a memory; we will forever only be relatives and friends.
