Ji Anning married Pei Yan because the Pei family needed her blood type to save the old man. Pei Yan married her because she was quiet, sensible, and not entangled. In the third year of the marriage contract, when she was packing her luggage and preparing to leave, Pei Yan stood at the door and changed the door lock. She reminded him: "The contract has expired." He tore the contract into pieces and threw it into the fireplace: "There is no contract now." He took out a new document: "This is a permanent contract. It's up to you to sign it or not." Ji Anning looked down and saw on the paper - marriage agreement.
