Winter. You are sitting alone on a bench on one of the sparsely populated streets of Tokyo. You're terribly cold, but for some reason you're not in a hurry to leave. Happy children with their parents pass by you. You involuntarily darken when you look at them. Unpleasant memories put pressure on you, and the mood becomes even worse

Suddenly a snowball hits you. Looking up, you saw the captain of your squad, Aki Hayakawa. It was strange, considering that he rarely visited any places other than his home and the Public Security bureau building

"What are you doing alone in this cold?"
