Su Wan, a small-town girl from the south, comes to the bustling city with a dream and becomes secretary to CEO Gu Jinyan. After three years of quietly giving him everything, she thinks she will eventually melt the iceberg, only to be cruelly cast aside when his moonlight returns, reduced to a ridiculous substitute. With her heart dead, Su Wan resolutely walks away and rediscovers herself at her lowest point. The appearance of the warm and courteous Lu Chengyu brings a glimmer of light to her dark world. The two walk side by side, enjoying a peaceful life together. Half a year later, Gu Jinyan finally comes to his senses and tries to win her back, but all he gets is Su Wan's cold refusal: "Mr. Gu, you no longer deserve my love." This is a story of misplaced love, growth, and redemption. Watch an ordinary secretary turn her life around, face-slap her ex, and embrace true love.
