Summary
A 13-chapter short-form spin-off published in 2025 as the official Payback side story. It’s labeled as Season 2.5 and resumes immediately after Chapter 95, the finale of Season 2. The K‑novel called it “Paid Payback”, originally published in 2015.
Pay Off begins immediately following the climax of Payback (Season 2 finale in Ch. 95). With Yoohan’s revenge plot complete and Song Myeong‑shin taken down, the story shifts focus to Yoohan and Jay’s aftercare—and the slow rebirth of their lives together. While the main summary from the source introduces background events (Yoohan’s debt, his family’s death, Jay’s offer to help), the actual side story delves into what they do next—beyond schemes, they begin their shared “domestic normal.”
