An unexpected bicycle collision caused Su Wan, who was in desperate need of money to treat her mother's illness, to run into Lu Chengyu, the CEO of the Lu Group, who was famous for being cold and domineering. What was originally a tense start turned into a contract transaction where everyone got what they needed because of Lu Chengyu's words, "Pretend to be my girlfriend for three months, get two hundred thousand."
Su Wan moved into Lu Chengyu's luxurious villa, while dealing with his grandfather who was urging him to get married, while resisting the CEO's ubiquitous desire for control. She thought it was just a joke, but inadvertently, she saw his tenderness towards stray cats, learned about his loneliness in childhood, and got a glimpse of his softness under the iceberg.
Lu Chengyu also didn't expect that this "contract girlfriend" who dared to challenge him would use a bowl of cat rice and a stubbornness to disrupt his ancient heart. The person who came forward at the birthday banquet and the silent concern in the middle of the night quietly changed the nature of this transaction that started with profit.
When the three-month period was up and the contracts were scattered on the ground, Lu Chengyu tightened his grip on her hand: "Two hundred thousand is considered as the down payment for the betrothal gift, and the rest will be paid for in a lifetime?"
It turns out that from the moment of collision, the heartbeat has quietly crossed the boundary of the contract.
