One day a nasty man shows up at Ushijima's office. Yuki, Ushijima's classmate from junior high school, comes to lend some money but rejected. 12 years ago, Ushijima was transferred to a new school and made friends with Yuki. Yuki was a kind boy and now a man with a good heart. However Yuki couldn't make a living and was picked by Gakuto brothers while freezing on the street. The Gakuto brothers are famous of cruelty. They pick homeless people on streets to dormitory and make them work very hard to pay a forced debt. Again Yuki comes to Ushijima for lending money, this time to save people in that dormitory.
