Kim Sun-yi, 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 back to the house in the country. Sun-yi recalls how 47 years ago, when she was a 17-year-old girl in 1965, she moved from Seoul along with her widowed mother and sister Sun-ja 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 landlord, Ji-tae, son of the business partner of Sun-yi's late father. Because of her delicate health, the beautiful yet introverted Sun-yi lives an isolated life without any friends. One day, Sun-yi discovers a feral boy of about 19 in their yard. His blood type is 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, 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, speak, write, and other human behavior so that he could one day live like a normal man. Chul-soo demonstrates unswerving loyalty and superhuman brawn, inspiring the envy of Ji-tae, who lusts after Sun-yi. The two eventually become close; as Sun-yi opens her heart to Chul-soo, 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 boy who risked his life to be with her, Sun-yi leaves him with a promise: "Wait for me. I’ll come back for you." In present day, Sun-yi 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 waiting all along. He reads her a book she had asked him to read all those years ago, as she falls asleep. The next day, she wakes up with Chul-soo nowhere in sight, and leaves with her granddaughter. They receive a call from the county asking about the property. Sun-yi tells him that she's not selling the place. Chul-soo stares from afar as the car drives away. A sequence in the ending credits shows Chul-soo building a snowman.
The film's music video featured John Park's single "철부지". "My Prince," the song that Sun-yi sings in the film, was released as a digital single and included in the soundtrack. It was composed by music director Shim Hyun-jung with lyrics by director Jo Sung-hee.

Reception
After premiering at number one in the South Korean box office with more than 100,000 admissions, A Werewolf Boy broke the 1 million mark after five days, 2 million after nine days, and 3.6 million in twelve days. Not only were these numbers remarkably high for November, considered a slow season for moviegoing in Korea, but it was also a rare feat for its melodrama genre. The film also has the distinction of setting a new box office record for "suneung day," the date on which high school seniors take their College Scholastic Ability Test. Each year large numbers of students book tickets for films in the evening after the exam has finished, but A Werewolf Boy's one-day score of 341,475 tickets on November 8 outpaced the totals of any film in previous years. On November 15, its 4.12 million admissions surpassed Architecture 101 to become the most successful Korean melodrama of all time. Ticket sales reached 5 million on November 18, 6 million on November 26, then 7 million on December 16, making it the third highest Korean top grosser of 2012, behind The Thieves and Masquerade, and also the fourth best selling film of the year overall. The film also became a sleeper hit when it was released in Taiwan on December 28, 2012, grossing NT$4 million at the Taipei box office after 17 days on release. The film also made its premiere in the Philippines on September 18, 2013 as part of the Korean Movie Festival 2013.
Alternate ending
After director Jo Sung-hee revealed during one of the film's Q&A sessions that they had shot an alternate ending, due to popular demand, the movie was re-released on December 6, 2012 with that ending. The alternate finale involves Park Bo-young's Sun-yi, and among the deleted scenes are moments from Ji-tae's childhood as well as more focus on the neighborhood in which the plot unfolds.
