The male lead, Du Zhongyun, was born into a small eunuch family in Chang'an City. His family was poor and he was accepted as an apprentice by Tang Yi, a medicine man. After discovering his talent, he devoted himself to managing pharmacy and practicing medicine to save people.
The second male lead, Li Chenxiang, was originally an abandoned child. He was handsome and clever and was adopted by the Li family (who had no children but gave birth to a son after adoption). He met Zhong Yun by chance.
"I want you to hold me tightly for the rest of your life."
"Chen Xiang, I love you." From the moment you came to the pharmacy covered in blood and wiped the blood off your face, I was so surprised that I fell in love with you.
