Baichuan is famous for the gourmet cuisines of Seven Chefs. For more than 200 years, the Seven Chefs are the only five-star chefs. According to the rules of the Chef Alliance in Baichuan City, if a chef wants to rank up, that chef has to challenge another chef of the same rank in a knife-stealing challenge. The restaurant of the loser will be shut down and the loser's name will be removed from the industry. All who challenged the Seven Chefs failed. But the head chef of Chunxing, Jiang Jie, managed to become a five-star chef through the knife-stealing challenge in under a year. Jiang Jie holds a grudge against Xue Congming for refusing to take her in. So, he decides to challenge the Xue Clan first.

On the way home, Li Nai, who faced setbacks in opening a restaurant, runs into Jiang Jie. Learning that Jiang Jie lives in the same block, Li Nai proposes to taste his cooking. After trying Jiang Jie's snakehead fish noodles, Li Nai realizes that her cooking skills are far from being able to reclaim her master's knife.

Li Nai's mistakes while preparing the staff meal made Jiang Jie furious. She argues with him due to differing opinions. Li Nai wants to resign. Jiang Jie wishes to make her stay. He uses the meal she owes him as an excuse to try the head chef set in Zhaoyeqing. Jiang Jie tells her that he didn't choose her to be the warehouse keeper to pick on her. It's because Li Nai has a keen sense of smell. It gives her an advantage when it comes to identifying ingredients. He rescinds her resignation application.

Zhao Jingjing and Jiang Jie formally meet at a dinner organized by people in the Alliance. Jiang Jie seeks out Zhao Jingjing alone and talks to her about Zhong Haiyang. Faced with Zhong Haiyang's vague responses, Zhao Jingjing already has a clear answer in her heart. She stubbornly believes that her father's heart only has Zhaoyeqing and not her as a daughter. In her sorrow and anger, she decides to take the initiative to challenge Jiang Jie in order to steal his knife.

On the day of the welcome banquet for Mr. Xu Kang, Jiang Xiu returns to the country. The Jiang family announces Jiang Xiu's appointment as the new head chef of Xijiangyue. However, at this critical moment, Li Nai suddenly receives news of Li Jidong's disappearance. Without even having the chance to greet her sister, Jiang Jie hastily leaves the banquet. With her father missing, Li Nai is consumed with worry.

After getting tricked by Jiang Xiu, Li Nai finds out that Li Ya is Jiang Jie's sister, Jiang Xiu. When they meet again, Li Nai is holding a grudge against her. Jiang Xiu challenges Li Nai to compete against each other with their sense of smell. Li Nai's sense of smell is a talent that she's proud of. But she loses to Jiang Xiu who's labeled as a genius.

Jiang Jie saves Li Nai from the reporters and sends her home. Then, he defends Li Nai in front of the media. Cui Can restores the broken knife from the Li family and finds out that it's the lost knife of the Li family that was once a member of the Seven Chefs. Li Nai realizes that she's the successor of the Li family under the Seven Chefs of Baichuan.

Jiang Xiu is in a bad mood. She plays a shooting game in the night market after getting off work early. Coincidentally, she encounters Cui Can. Cui Can pursues Jiang Xiu persistently. He keeps her company when she's unhappy. Jiang Xiu becomes happier thanks to his accompaniment.

Li Nai goes home disappointedly. On her way home, she encounters Jiang Jie. She uses the opportunity to ask Jiang Jie to teach her. Jiang Jie imparts his experience and techniques to Li Nai. They spend the night in the kitchen. In order to find the flavors of nature and defeat Ge Qunshan, Jiang Jie drives to the suburbs to camp in the wild and experience the flavors of nature together with Li Nai.

After days of being open without any customers, Chihuanghun finally welcomes its first table. The birthday girl, Zhou Zhou, wishes to have Western cuisine, and Li Nai's innovative fusion of Western and Chinese dishes impress her greatly, and she offers to promote her restaurant. Finally, the new establishment begins to see some success. Li Nai is thrilled and over the moon. She goes to Jiang Jie and is invited to enjoy a perfect dinner at his place. However, when Li Nai enters Jiang Jie's room to fetch some wine, she spots various photos on the wall detailing Jiang Jie's plan to steal knife.

Chihuanghun gets first place in various rankings a month after its opening. Li Nai feels troubled because she is afraid that Jiang Jie will find out. Cui Can asks his sister, Cui Jing, to help him cover up Chihuanghun's owner's information so Jiang Jie won't find out. Xue Congming lies to Li Nai and says he is traveling to Sanya for a few days, but Zhu Hao says she saw him at the city hospital. Li Nai and Cui Can see Xue Congming lying in the oncology ward. They are angry about Xue Congming lying to them, but they also feel sorry for him at the same time.

Jiang Jie's grandfather finds out that Li Nai is the successor of the Li Clan. He plans to bring Jiang Jie back to the family after he steals their knife. Jiang Xuyang thinks that his position has been threatened. Li Nai and Cui Can lower their guard after finding out that the ingredients that they received were wrongly delivered by Xijiangyu. They devote themselves to preparing the dishes for the challenge.

Jiang Xiu apologizes on behalf of his brother for stealing Xue Congming's knife. Meanwhile, Jiang Jie questions Cui Can about his relationship with Jiang Xiu. Jiang Xiu says he has a clear conscience and uses the opportunity to see what Jiang Jie thinks about Li Nai.

Li Nai wins the knife-stealing challenge due to the vote fraud Cui Jing had committed. Although Li Nai wins the challenge, her master leaves her for good. Chuncheng stopped operating. Zheng Fangxing is angry about Li Nai's betrayal. The media points their fingers at Cui Jing for committing fraud. Cui Can finds his sister to get an explanation.

Ge Qunshan, who is in charge of the village canteen, accidentally injures his hand. The cooking responsibilities are then handed over to Jiang Jie. Consequently, Jiang Jie starts living in the Yu Village. Two months later, Zhao Jingjing has already joined Chihuanghun, working alongside Li Nai with the shared goal of abolishing the knife-stealing challenge. The business of Chihuanghun is also gradually thriving.

Caobaiyu has accepted the Five-Star Alliance's review. Cui Can becomes a reviewer and hires a girl to pretend as his girlfriend to have a meal at Caobaiyu. Coincidentally, Jiang Xiu sees them. Jiang Xiu is angry because Cui Can has not contacted her for two months after his disappearance. Jiang Xiu breaks up with Cui Can after quarreling with him. Jiang Jie accidentally hurts his leg at Yu Village, and Li Nai takes care of him.

Chihuanghun receives a notice of review from the Five-Star Alliance. If Chihuanghun passes the Five-Star Alliance's Review, it will be eligible to steal the knife from the Jiang family. Jiang Jie promises to join Chihuanghun if it passes the Five-Star Alliance's Review. Jiang Xu Yang is concerned that Chihuanghun will jeopardize his plans to open a chain store. He collaborates with Cui Jing to obstruct Chihuanghun from passing the review. However, Cui Can accidentally discovers this matter.

Jiang Jie is worried that Jiang Yuanfeng might harm Li Nai. He rushes to Chihuanghun. He finds out that Jiang Yuanfeng hired some goons to wreck her shop. To go against Jiang Xuyang, Li Nai enlists the help of Jiang Ziqing.

Jiang Jie and Li Nai are in the middle of their love bubble. Li Nai prepares a lunch box for Jiang Jie. Jiang Jie prepares a cake for Li Nai. Li Nai doesn't want her employees in Chihuanghun to find out about their relationship for now. They have no choice but to date each other in secret. But Zhao Jingjing, who has a keen sense of sight, saw through them long ago.

Li Nai and Jiang Jie enter the Jiang Residence, hand-in-hand. As the host of the banquet, Cui Can devises a secret plan with Li Nai to clear Jiang Yuanshan's name. They tell the story of the Yao family in front of the guests to imply the Jiang family's history. They invite Ge Qunshan to the banquet behind Jiang Jie's back. Jiang Xuyang intends to borrow Jiang Jie's power to topple Jiang Ziqing.

Chihuanghun issues an official knife-stealing challenge against Xijiangyue. Although the opponent is her own brother, as the head chef of Xijiangyue, Jiang Xiu takes the challenge seriously without going easy on him. Meanwhile, Jiang Jie and Li Nai practice seriously at home. They experiment with their menu to prepare for the challenge.
