From back alley brawls to bashful bonds, two former-delinquents face their next fight: long-term relationships. During her high school years, Takebe was the top dog at her school. But with her old friends now living as happy adults, Takebe was faced with an impending sense of crisis. Takebe convinced herself to quit delinquency, but then she runs into her old rival, Soramori. After losing another fist-fight against Soramori, for some reason or other they reconciled by becoming a dating couple. What kind of relationship did the two of them have back in high school? And will Takebe ever manage to graduate from delinquency...!? Note: Chapter 2 is presented in two parts, and four volume-bonus chapters are included in the total chapter count.
