He Shaoran had dinner with his father, mother, and friend Luo Sen, who had just received the Lifetime Achievement Award of the Uniasia Awards, at a restaurant. Yong Qi and his colleagues were also shooting a burger commercial next door, but the hard-working commercial plan was ruined by the sprinkler. The culprit of all was actually Shao Ran from the box next door. Shao Ran jumps to Lome Advertising Company and replaces the original AD Uncle Kuan, causing dissatisfaction among colleagues in the sales department. Because of being late, Yong Qi mistakenly thinks that Shao Ran is a newcomer AE, and enthusiastically helps Shao Ran. After knowing Shao Ran's AD identity, Yong Qi felt embarrassed and angry, so he joined the ranks of excluding Shao Ran.

Shao Ran competes with the entire sales team on the new car advertisement, and the loser will leave the job. Yong Qi's secret weapon to win is Director He. In order to invite Director He, who refused to shoot commercials, Yongqi climbed the mountain with Director He and his friends, and became friends with Mrs. He on the way. Through divination, Wan Ying discovers that Yong Qi, whose luck has been very bad, will change his luck. He Zhuli stalks Luo Sen, Luo Sen has no choice but to ask Shao Ran for help, but He Zhuli tells Shao Ran that the person she really likes is Shao Ran. Wan Ying thinks that Luo Sen is too careless, so she tricks Luo Sen when picking up the car.

Yong Qi used science fiction to communicate with Director He's son, whom he had never met before, and asked him for help, but unexpectedly, he was let go. At Shao Ran's request, Director He agreed to take the commercial for Yong Qi. During the pitch, Julie chose Shao Ran's project. After Yong Qi learned of Shao Ran's true identity, he left angrily and accidentally fell down. Shao Ran rescued him, and they fell down the stairs together with Yong Qi and collided. The fate of the two actually switched when they collided, and their fortunes were reversed. Lucky Shao Ran encounters a series of unlucky things.

Shao Ran suffered from a fever within one day, his team members resigned collectively, lost the car case of Julie Company, lost 3 important cases in a row, the car stereo was stolen, and failed to visit customers one after another. It turned out that Yong Qi was appointed to take over the lost hamburger commercial. Not only that, but Yong Qi and his colleagues also received 3 important cases. Luo Sen reminds Shao Ran that an astrologer had predicted that Shao Ran's luck would be reversed. Although Shao Ran didn't believe it, he went to Wanying's astrologer with Luo Sen. Shao Ran met Yong Qi in the astrology hall, and knew that the person who took away his advertisement was Yong Qi, and gradually changed his original opinion under Wan Ying's persuasion. With the decline of traditional martial arts, Tian Nan's Zhishan Martial Arts Academy is very deserted. The only apprentice learning martial arts is because he is forced to lose weight.

Shao Ran finally believed in the fact that his and Yong Qi's fates had changed. Yong Qi agrees to exchange luck with Shao Ran. The two fell down the stairs again but failed. They tried many methods but failed, during which time they cleared up their past suspicions and their feelings grew. Yong Qi succeeded in persuading his colleague to return to work, and Shao Ran finally figured out the key to the exchange of luck and the exchange was successful. Both of them have returned to their original lives, but their moods are already different. Wan Ying and Luo Sen drink together, and the two have an accident when they are drunk and unconscious. Yong Qi was framed by a client and was fired by Shao Ran.
