Four years ago, due to family changes and coercion by Zheng Mingyuan, Lu Ze carried huge debts and left without saying goodbye, parting ways with his lover Su Wanqing, and raising the Ragdoll cat Pudding alone. Four years later, Su Wanqing was airdropped to become Lu Ze's planning department director, and former lovers became superiors and subordinates. Manager Liu and Zhou Hao successively set traps, spreading debt rumors and stealing plans. Relying on Pudding's clues, Su Wanqing investigated the past, and the two untied their four-year knot. They teamed up to root out the mole and won a tens-of-millions bidding project; Lu Ze paid off all his debts, and his career and love both reached a happy completion.
