Besides, the last one who came back was the prince. To be sure, after the prince returned to the original time and space, he must have missed Kappa too much and died of double suicide without the company of Furong. As for whether Rong Tai has the memory of the prince, or whether the prince's soul has crossed to Rong Tai, I personally think it is the latter. Finally, the man waiting for Kappa in the park looks like a prince from the way he stands. As soon as he took Kappa's hand, the picture immediately turned into a prince in an ancient costume, and the people around the park disappeared, which proved that this was actually the feeling that Kappa was familiar with Wang Shizi Li Ke when he held the man's hand in front of him, leaving rolling tears.
The last narrator, on the one hand, said "300 years" in the tone of Prince Shizi, on the other hand, said "I still love you" in the tone of Lotus. In fact, it also means that the four bodies and two souls have been deeply in love with each other, regardless of the Prince or Rong Tai, regardless of the Lotus or Kappa, and finally they are really together. This is my understanding.
Anyway, you don't have to worry about the problem that lovers can't be together, and you don't have to worry about whether Prince Shizi stayed in ancient times and suffered from acacia. The final editing of the director's DVD shows everything-the original five people in the tower room took a group photo, and Prince Shizi and his party disappeared because they returned to the original time and space, but the last shot, Prince Shizi, appeared in the photo again. This means that the prince is back, which is true.
This is my conclusion from comprehensive analysis, and I hope the landlord can be satisfied.
