Jiang Yanzhou returns from purgatory with a past life full of sins and endless remorse. Deeply entangled in underworld conflicts in his past life, he was plotted against by enemies and with his own hands dragged Xu Xingwan into the abyss, resulting in a lifelong regret. Reborn back at the beginning of the tragedy, he resolves to let go of dark killings, while laying out business wars step by step to settle the deep-laid conspiracies of He Chong and Lin Shuo and complete his self-redemption; while suppressing surging affection, cautiously drawing close to and silently guarding Xu Xingwan. Time and again fated encounters, round after round of crisis confrontations, love and hate pulling at each other, guilt and heartbeat entwined. He walks between the cracks of black and white, staking everything, just to break the established destiny, repay his debts, and protect his girl in peace.
