To save her family, Lin Chuxia takes the place of her runaway sister, signs a three-year marriage contract, and marries Gu Linzhou, the most powerful man in the capital.
On their wedding night, they agree on three rules: separate rooms, no interference, and keep the marriage secret. She accepts calmly, planning to take the money and leave when the time is up.
Then she gets pregnant unexpectedly, and he coldly accuses her of scheming. Her heart dies completely, and when the contract ends, she disappears without a trace.
Three years later, at the finale of International Fashion Week, rising designer "Summer" shines in the spotlight. She walks out hand in hand with two children as adorable as dolls and comes face-to-face with her ex-husband, who rushes toward her in a disheveled state, eyes bloodshot.
"Mrs. Gu, have you had your fun?" he rasps.
She smiles and waves her empty ring finger. "Mr. Gu, we're divorced."
Behind him, his assistant frantically chases two adorable little ones dashing around the venue. The boy clutches a tablet and calmly analyzes, "Daddy's net worth passes, but his emotional intelligence test doesn't." The girl blinks her starry eyes. "But he's handsome! Mommy, you can give him extra points!"
Later, everyone in the city knows that the cold, ruthless president of the Gu Group has suffered the greatest defeat of his life. By day, he dominates the business world; by night, he has to memorize The Good Dad Handbook and find every possible way to win back his ex-wife, who has two genius babies and has completely forgotten him.
What began as a cold transaction of mutual benefit
has left him unknowingly bowing to her, and loving every minute of it.
