Kayo Iwasawa is a close friend who lived next door since my childhood, and she is now married. But it wasn't until she married someone else that I realized I had liked her for a long time. After a while, I also got married, but I always regretted not confessing to her earlier. Some time later, Kayo returned to her parents' house, and seeing her every day through the window made me feel incredibly emotional. After going to her house to hang out and talk, it seemed like she also liked me back then, and I ended up confessing everything I had kept hidden for so long.
