Director Sung-heui Cho once said: "Love is a fantasy. The movie tells the audience sadly about the "beautiful love" that no longer exists in the world. I hope that through the real friendship and love of the two people in the film, it will be passed on. To the audience, the brilliance of humanity that has long since disappeared in real life. At the same time, I hope that the movie can make the audience yearn for the time, the people.and the long-awaited extravagance."
In the film, Song Joong Ki still dedicated to the audience a unique alternative youth cruel story. Since he played the role of a "wolf", the buying point is no longer a beautiful boy, and there has been a major reversal in styling. This character lacks lines in the film, and almost only uses howls and body language to show wolfish emotions. Song Joong Ki debuted with disheveled hair and dirty appearance. In this regard, Song Joong Ki said, “There is no secret, just keep recalling the lines in my heart. The same is true when the wolf boy is undergoing training. I place more emphasis on inner drama than my eyes. Because I think this is neither a horror movie. It’s not a suspense film, but a romance film. The most important thing is to get closer to the heroine. The more troublesome thing is the process from crawling on all fours to walking on feet. I tried very hard to follow the steps until Able to conquer the entire crew and put an end to NG."
Park BoYoung, who plays the heroine, has collaborated with Song Joong Ki this time in Love of Man and Wolf. She shows a very delicate feminine charm. Director Sung-heui Cho once said, "The first time I saw Park BoYoung, I felt that the girl who walked in was the girl from "". The appearance was indifferent but the heart was just right."
