Junko (Mizuhara Biyi) is a rich lady born with a golden spoon. One day, she came to China to collect inspiration for her paintings and accidentally met a Chinese youth named Tan Dazhi (Yang Juncheng). The handsome and upright Tan Dazhi captured Junko's heart at once. After returning to Japan, Junko still couldn't forget Tan Dazhi, so she decided to go to China again for Tan Dazhi. However, what Junko didn't expect was that this second trip actually made her a witness to Tan Dazhi's wedding. But even so, Junko's love for Tan Dazhi did not waver at all. She was even willing to give up everything in Japan for this man and stay in China. Tan Dazhi received a letter from Junko's father, asking Tan Dazhi and Junko to spend 24 hours alone. Tan Dazhi was puzzled by the meaning of this request.
