In Shanghai in the early spring of 1925, the French Concession was filled with a prosperous atmosphere of a blend of East and West. The Yu Family Mansion is holding a 60th birthday party for Mr. Yu, where celebrities from all walks of life gather.
- Yu Wanting, as the only daughter of the Yu family, performed the piano piece "Moonlight" at the request of her father, but because she was disgusted with this arranged display, she deliberately played a few wrong notes and then left the performance with an excuse.
- In the back garden of the mansion, Wanting encountered Qin Mochuan who had climbed over the wall. She mistakenly thought it was a thief and raised the vase in self-defense. Qin Mochuan explained that he was an invited guest and got lost here. The two looked at each other for the first time under the moonlight and were amazed by each other.
- After the banquet, Mr. Yu informed Wanting that he had arranged a marriage for her with the warlord's son. Wanting fiercely opposed it but was suppressed by her father.
