I have seen this film twice. First, the hero is not dead, but frozen. There are instructions at the end of the film. This is the part where he and his good friend slept on the road after they left Sofia. From there on, the dreams behind him were all designed by him! Second, because cats are a symbol of freedom in the eyes of westerners, and cats are sensual and pure animals, David likes a free life as much as Sophia ... Remember the first time David walked into Sophia's residence? Sophia said that she likes a free life ... with some details ... it can be seen that Sophia likes a free life. David's family environment should make him feel bound ... so he has always wanted to escape that feeling of being bound and live a free life. ......
