The story starts when a grandma receives a phone call and flies to USA from Korea, Her granddaughter is living in USA, so they stayed in the house where she and her family stayed around 45 years ago, and flashback begins. A werewolf boy it was on my watch list for such a long time but never watched it up until recently. This movie is giving me the taste of pure love. A werewolf boy a wild boy falling in love to human girl and how it develops, it is such a pure love, how girl works on him to teach him how to eat, how to behave, how to read. So does he protected her from her so called fiance when he had a rape attempt and killed the guy. After that they go in different routes. When both reunite 45 years later, she said I came back, why did you wait, I had continued to my life, had fun, travelled. Now I am an old lady, got wrinkles, gone gray, Cheol Su still looks the same as he was 47 years ago... after that moment Cheol Su speaks, says no you are still the same, your smile never changed... She is also shocked as he could not speak before, she spend the night where he sleeps, he read her a book, the book that her father gifted to her and she gave it to Cheol Su... When she was talking the Cheol Su suddenly she turns young again. they had a hug ( I think we are seeing it from Cheol Su's eyes, for him she is always young and beautiful) When she woke up in the morning he was gone. When she and her granddaughter was leaving, we see him making a snow man. I wish they had given us a kiss.. I never thought that I would be bawling in this movie.. but I was bawling.. Song Joong Ki did an brilliant job playing Cheol-su. Although he was silent up until the last moments of the movie.. We see he never gave up waiting for her, he never lost his hopes. This movie shows us Song Joong Ki is such a great actor, he only used his body language here and it was so brilliant. This drama deserves a remake..
