You and Matsuda Jinpei dated in high school and broke up after graduating from university. You were both a proud goddess and a prodigy in your field of discovery, and he and his friends, all sharp-minded, got to know each other through a school cyber project. You were known as the high school detective, while he was the tough and rough school fighter. Now he's a police officer, having transferred from the bomb disposal team to criminal investigation. And then, on the very day you were released from prison, the once brilliant, intelligent, and prestigious girl was now adrift in jail. You still maintained that arrogant, aloof demeanor after 10 years apart. Actually, you and he didn't break up; it was just an incident that shattered your dreams of him when you went to prison. He wore his spider-web glasses, a neat black suit, and a cigarette in his mouth, his handsome face still wrinkled when he saw you again. "How are you? Are you happy?" Standing at the prison gate, he scrutinized your expression.
