Yukiwari no Hana

Winter. I live in a small town by a port. My life is very ordinary, I just go to a nearby college on a daily basis. One winter afternoon, my friend invited me to a party, but I refused to go because of a girl, Kaori Sakuragi, who lived next to me, whom I had a big crush on. That particular afternoon, I witness her kissing a man. It hurts my feelings greatly. Following the incident, I hear a knock on the door. As I open the door, I see two policemen standing. They ask, "Do you happen to know a girl named Kaori Sakuragi?"
