Coincidentally, I discovered Beauty Inside after reading David Levithian's Everyday. I loved that book and somehow, that book has the same premise as this movie. Who cares whichever came firat, I judged them separately. Also, the movie is a remake of an American movie with the same title. B The Story It's crazily genius. The story is definitely one of the very few of its kind. In the story, the main hero at least have a personality of his own since he only started changing faces when he reached a certain age. Woo-jin at least has his own personality, talent, and skills before he lost his physical appearance and started changing. Yi-soo, on the other hand, lives a normal day-to-day life and getting involved in a crazy circumstances like this entails difficulties. The story effectively depicts a story of a person finding true love and belongingness in this world despite his "illness". At the end of the day, it doesn't matter whether the whole world is against you as long as there is some people who accepts you through and through. The Cast Just having Han Hyo-joo is already enough for me. But of course, the premise requires the movie to have a lot of actors/actresses to act as the hero. There's plenty of them but it helped that known actors portrayed the hero in the crucial scenes in the story. Most mermorable performances for me was from Park Seo-joon, Lee Jin-wook, Lee Dong-wook, Go Ah-sung, and of course Yoo Yeon-seok. There were many others who played as the hero and made their very short appearance worthwhile. Overall I'm a total sucker for everything crazy and supernatural like this. I already love the story without watching it yet so there's not much work to be done for me. But, what I really appreciate is the watly the story is execited when such premise is already complicated. I love how I felt the sincerity and desperation of Woo-jin and Yi-soo's love.
