Zhuang Yu, a professor of botany who is dedicated to the cultivation and research of Artemisia annua, is devoted to scientific research and indifferent to worldly fame and social interaction. This inadvertently hurts Yu Meiren, a country girl who had a crush on him many years ago. Many years later, Yu Meiren obtained a doctorate in ornithology with excellent results. Because she was unwilling to bear the pressure of scientific research, she switched to become a fashion blogger and accidentally had a feud with Zhuang Yu again. Zhuang Yu went to Qingshui Village for field research and happened to live in Yu Meiren's homestay. With the help of Yu Meiren, Zhuang Yu's scientific research progressed smoothly, and he also felt the love and warmth that plants could not give from Yu Meiren. Yu Meiren was also infected and inspired by Zhuang Yu's persistence in academics, and was determined to shoulder the responsibility and use what she learned to feed back to her hometown. One of them kept forging ahead to overcome difficulties, and the other actively advocated environmental protection. Although the two young people had different starting points, they walked hand in hand with love because they had the same ideal of building the motherland and the hometown.
