...is a 2012 South Korean fantasy romance film in which a beautiful teenage girl is sent to a country house for her health, where she befriends and attempts to civilize a feral boy she discovers on the grounds. But the beast inside him is constantly waiting to burst out.

Synopsis

Kim Sun-yi(Yeong-ran Lee), an elderly woman in her sixties living in the US, receives a phone call about the sale of her old family home back in South Korea. Returning to her homeland, she's met by granddaughter Eun-joo, and they drive to the house in the country and stay the night. Sun-yi recalls how 47 years ago when she was a teenage girl in 1965, she moved from Seoul along with her widowed mother(Young-nam Jang) and sister Sun-ja(Kim Hyang Gi) to a remote valley to undergo a period of convalescence after suffering problems with her lungs. The Kims lived in genteel poverty at the mercy of their arrogant and foppish landlord, Ji-tae(Yoo Yeon-seok), son of the business partner of Sun-yi's late father. Because of her delicate health, the beautiful yet introverted Sun-yi(Park Bo-young) lives an isolated life in the country home, without any friends her age.

One night, Sun-yi glimpses a shadow in the outhouse; the next day, she discovers a feral boy of about 19 crouching in their yard. The boy's body temperature is 46 degrees Celsius, his blood type unidentifiable, and he can neither read nor speak. Even though he behaves like a wild beast, Sun-yi's kindhearted mother adopts him and names him Chul-soo(Song Joong-ki), assuming he's one of more than 60,000 children orphaned in the Korean War.

At first Sun-yi considers him a nuisance, but eventually has fun taming him according to a dog-training manual. She teaches him how to wait patiently before a meal, how to wear clothes, how to speak, how to write and other human behavior so that he could one day live like a normal man. Chul-soo demonstrates unswerving loyalty and superhuman brawn, thus inspiring the envy of Ji-tae, who lusts after Sun-yi.

As Sun-yi attempts to "civilize" the beast, the two eventually become very close. Sun-yi opens her heart to Chul-soo, and he in turn falls in love with her, the only person to ever show him affection. But their relationship is fraught with difficulties, as Ji-tae begins to cause trouble. Feeling threatened, Chul-soo lets loose his bestial instincts, and in their fear the town villagers turn on him. In order to save the life of the boy who risked his to be by her side, Sun-yi leaves him with a promise: "Wait for me. I’ll come back for you".

Returning to present day, Sun-yi decides to stay the night. In the middle of the night she walks into the shed to find Chul-soo sitting there, still as young as he was 47 years ago. He hands her the note that she wrote. She realizes that he's been there waiting all along. He reads her the book that she asked him to when he can speak, as she sleeps. The next day she wakes up with Chul-soo nowhere in sight. She leaves with her granddaughter. In the car they receive a call from the county asking about the property. Sun-yi tells him that she's not selling the place and hangs up. Chul-soo stares from afar as the car drives away.

A sequence in the ending credits shows Chul-soo building a snowman.
