    Summary

    Red wanted a better life for his six-year-old brother, so he saved his money, scored a new job and hauled the temperamental brat halfway across the city to a new apartment, far away from the cesspit they once called home. Falling in love with his punny next door neighbor wasn’t part of the plan.
