Dr. Jiang, Please Stop Your Duplicity.

Qin Tie and Jiang Xin, a pair of childhood sweethearts who were forced to perform a "baby marriage", signed a one-year "cooperative marriage" contract. They thought this was a stop-gap measure to deal with their families, but in the process of "acting" as a loving couple, their hearts had already moved without even realizing it. When the contract expired, old love struck, and the truth surfaced... They discovered that this contract had already been signed into their hearts.
