Lin Xiaoxing, a newcomer with a unique brain circuit and a "confusion buff", broke into the Lu Group by accident after graduation and became an intern in the President's Office. Her daily routine in the workplace can be called an "unexpected collection": when delivering documents, she gets the takeout order by mistake, when sorting out information, she mixes confidential contracts into the waste paper pile, when receiving customers, she admits the wrong partner... But this unadulterated "brainless" and sincerity, like a ray of sunshine, accidentally shines into Lu Tingyuan's frozen world.
Lu Tingyuan, known as "Iceberg Yama" in the business world, has been in charge of the Lu Group for five years. He is known for his iron-fisted methods and zero error tolerance, and everyone around him keeps a distance from him. He was used to precise calculations and false flattery, but his calmness was broken by Lin Xiaoxing's "accidents" one after another - coffee was spilled on an expensive suit, but he didn't get angry; the contract was almost lost, but he found it funny; he even admitted to a wrong competitor, but still managed to promote a new cooperation.
From the initial "disdainful tolerance" to the later "subconscious protection of shortcomings", Lu Tingyuan found that he was increasingly inseparable from this confused girl. And Lin Xiaoxing was also getting into trouble and being tolerated again and again, and gradually saw the gentleness behind the mask of President Bingshan. When workplace strife and family doubts hit, Lin Xiaoxing used her unique "brainless" method to resolve the crisis, while Lu Tingyuan completely took off his armor and was willing to become a "wife-protecting demon" for her. This love that started out as an ulterior motive but ended as true love proves that the purest sincerity can eventually melt the hardest iceberg.
