Fang Zheng is an ordinary herbalist who works in the time-honored herbal restaurant "Guiyuantang". One day, he discovered that his boss's daughter Lin Wanqing looked exactly like his sister who had died many years ago. Out of missing his sister, Fang Zheng began to silently pay attention to Lin Wanqing and protect her health with carefully prepared medicinal meals. However, Lin Wanqing's father Lin Zhentian believed that Fang Zheng had ulterior motives and made things difficult for him at every turn. On the surface, Fang Zheng plays with people's hearts and uses various means to make Lin Zhentian change his mind. In fact, he is honest and honest at heart and just wants to use his ancestral medicinal diet skills to help others. As Fang Zheng's reputation for herbal medicine gradually grew, jealousy among peers and business competition ensued. Zhao Mingyuan, a villain with a conflict of ideas, believes that medicinal diet should be commercialized and mass-produced, which clashes fiercely with Fang Zheng's insistence on traditional craftsmanship. In the atmosphere of daily healing, Fang Zheng warmed people's hearts with bowls of medicinal meals, and gradually unlocked his inner obsessions, understanding that everyone is an independent individual and not someone else's substitute. In the end, he won respect with his sincerity and skills, and found his true happiness.
