The story takes place in a hospital called "Renhua". Ye Chunmeng (Bai Baihe), who was born in a humble family, relied on her own efforts and struggles to overcome all difficulties and finally became an intern in the hospital. This hard-won job opportunity and the strict and cruel elimination system in the hospital put Ye Chunmeng under tremendous pressure. Zhou Ming (Lu Yi) is Ye Chunmeng's mentor. In the hospital, his black belly and poisonous tongue are known to everyone. Although Zhou Ming has always been very harsh to Ye Chunmeng and his words are not polite, he actually admires this hardworking and serious girl in his heart. After a while, the two people with different statuses developed feelings. Among Chen Xi (Jiang Shuying) and Bai Xiaojing (Zhang Zixuan), who are also interns, Ye Chunmeng always feels that she is inferior. In the cruel workplace, can she overcome her inferiority and fight for a bright future?
