A werewolf boy(SONG Joong-ki) was wasted by the world and lives in the wild and a lonely girl(PARK Bo-young) lives with her mind closed to the world. The boy meets the girl. She remembers a boy she knew half a century before. Moving to a peaceful village when she was a girl she discovered a “wolf boy,” hiding his large, contorted body in the darkness. The girl, now a woman, has never been able to purge the images of his wild eyes and animal-like behavior from her mind. She teaches the boy how to live in the society, then they gradually understand each other. Bothered by the way the wild boy behaves, she teaches him to wait for food, how to wear, how to speak and how to write one after another. Later, she opens her mind to the naive boy and finally feels the emotion of love for the boy, who was the first human who held out a hand to her. One day, the boy accidently reveals the hidden instinct of the beast when endangered, and unintentionally scare people. Even in such a situation, he tries to protect the girl. Agonized by the reality that they cannot stay together, she leaves him behind making a promise she cannot keep. “Wait for me. I’ll come back for you.” Directed by JO Sung-hee, the director of Don't Step Out of the House (2009), which won the Best Film Award at the 10th Jeonju International Film Festival, A Werewolf Boy was officially invited to the Open Cinema section of the 17th Busan International Film Festival, the Dragons & Tigers section of the 31st Vancouver International Film Festival and the Contemporary World Cinema section of the 37th Toronto International Film Festival.
