Su Wanwan, a confused girl who just graduated, accidentally submitted the wrong resume and became the personal assistant of Fu Sinian, the coldest and least womanizing president of the Fu Group in the city. On her first day on the job, she spilled coffee on the CEO's suit, took the wrong important documents, and walked into the wrong conference room. Oolong incidents occurred frequently, but they accidentally poked Fu Sinian's heart that had been dusted for many years.
In order to avoid family marriage, Fu Sinian proposed a contract marriage and made the confused assistant his nominal wife. Living under the same roof, Su Wanwan's clumsiness, cuteness, and gentleness melted Fu Sinian's iceberg little by little. He changed from the initial indifference to a wife-loving man who protected his shortcomings in everything and pressed on every step of the way.
The two fight side by side in the workplace, get along sweetly in life, and experience misunderstandings, love rivals, and family obstacles. In the end, their contract turns into true love. The confused assistant completely captures the heart of the domineering president and begins the rest of his life as the ultimate sweetheart.
