Seon Jin-Woo’s life takes a sharp turn when someone he once helped vanishes—leaving him stuck with a mountain of debt that isn’t even his. Refusing to give in, Jin-Woo stands his ground. But loan shark Seong-Hyeon has other ideas, pressuring him to seal an unusual deal: a contract that uses his very body as collateral. Which begs the question, how far are you willing to go to pay for someone else’s mistakes?(Source: Lezhin US) Note: - Chapter count includes a prologue. - Part of Lezhin's Gwanggong Collection (광공단편선). A gwanggong (광공, hanja: 狂攻) character is obsessed with the object of their desire, similar to the Japanese "yandere". Scanlations have erroneously translated this to "GwangGong Apartment/Industrial Complex", which may have caused confusion.
