At the age of twenty-two, Jiang Qingli lost both love and dignity. Her mother's hospital bed was a burden she could not shirk. When desperate, Shen Yucheng appeared. He is an academic leader and the mentor whom his ex-boyfriend Wen Yan admires. She offered herself in exchange for life-saving money. He gives shelter and fills the silence of middle age. This transaction should have paid off, but instead it gave rise to unnecessary greed. When "Professor Shen" becomes "Yucheng", when the transaction is sincere, in this dangerous game that uses life as a chess board, whoever makes the first move will lose everything.
Purpose: Amidst the huge class differences and secular prejudices, how does an ordinary girl protect her self-esteem, pursue her self-worth, and complete her growth and transformation from dependence on love to independent personality.
