Rong Yan is Fu Liancheng's little assistant. In order to get a large sum of money, she becomes his lover after spending a night together, solely because Rong Yan has a bottomless-pit-like family. Rong Yan has always been clear about her position, but still fell in love during their time together. Just as she wants to open her heart, Fu Liancheng signs a contract with her instead: whenever he calls, she must be at his beck and call. When the contract terminates, Rong Yan leaves without the slightest attachment, determined that they owe each other nothing.
