Lin Luxi, an ordinary girl, unexpectedly signed a contract with school sweetheart Lu Yanting as a "mutual doting partner." The contract stipulated that the two must dote on each other, and whoever was sincere first would lose.
At first, Lin Luxi just wanted to use the contract to enjoy the gentle service of the school grassroots, while Lu Yanting watched the game coldly.
However, with their daily sweet interactions, the two gradually began to act fake, but their respective secrets and fears made sincerity dangerous.
When Lu Yanting's wealthy fiancée appeared, Lin Luxi realized that there was a deeper conspiracy behind the contract - she must guard her heart, otherwise she would be doomed.
