This is a story about "disguise" and "being seen through", and "contract" becoming "sincerity". When the energetic "scumbag" girl signed a "love counseling contract" with the legendary aloof and abstinent senior in order to keep her credits, the two performed heart-pounding sweet scenes on the natural stage of the campus. They tricked each other and saved each other. In the end, they found that the sweetest thing was not the contract, but the person behind the contract.
