Shen Qingwan's mother was seriously ill, and the 300,000 yuan operation fee overwhelmed Shen Qingwan's life. When she was desperate, she signed a contract and became the "contract girlfriend" of Lu Group CEO Lu Siheng. That man was as cold as an iceberg and set three iron rules for her: don't cross the line, don't interfere, and don't expect anything.
Shen Qingwan thought that as long as he kept his job, he would be able to leave with the money in a year. But she didn't know that Lu Siheng chose her because she looked like his mother who committed suicide - she was just a substitute.
When she showed her talent in the workplace and conquered the board of directors with her design, Lu Siheng's indifference began to loosen. But just when she thought the iceberg would melt, the truth cut through everything like a sharp blade: Lu Siheng had always regarded her as a substitute for another woman.
At the same time, a commercial hunt quietly began. Shen Qingwan discovered that he was not only a substitute, but also the most critical piece on the chessboard.
The deepest affection in this world is knowing that you are a substitute, but still being sincerely moved.
