Liu Rushi and Fu Xizhou, two strangers bound by family interests, signed a three-year contract marriage. She is a down-and-out socialite, and he is a ruthless businessman. They both think that the other is just a stranger who is greedy for profit. It wasn't until one day that Fu Xizhou saw his half-length portrait in Liu Rushi's study and he was shocked to realize that they had known each other ten years ago, but they had forgotten each other. One is the girl who saved the boy who fell into the water, and the other is the boy who has remembered his benefactor for ten years. The gears of fate have already turned, but neither of them realized that what each other has been looking for is the person next to them.
