Liu Xintong (Zhou Dongyu) is an ordinary girl born in a poor family. However, the tight life did not wear out her enthusiasm and expectations for the future. On the contrary, the experience of life enabled her to always maintain a positive and optimistic attitude. By chance, Liu Xintong and her mother moved into the home of millionaire Ji Baijun (Feng Dalu), where Liu Xintong met Ji Zhenyu (Jia Jinghui) and Ji Zhizhen (Ye Qing). Ji Zhizhen has lived in a pampered life since she was a child. She is a thorough daughter of a rich family. She is infatuated with a man named Li Yaonan (Chen Xiao). However, the appearance of Liu Xintong made Ji Zhizhen begin to feel that she would take away the only thing she cherished. Sure enough, Li Yaonan fell in love with the strong and cheerful Liu Xintong. This unblessed love made Liu Xintong's situation in the Ji family very embarrassing.
