The narrative follows a reclusive and sickly teenage girl named Soon-yi (Park Bo-young), who moves with her family to a quiet country house for the sake of her health. While exploring the property, she discovers a feral, mysterious boy (Song Joong-ki) hiding in a barn. He displays wolf-like instincts: he lacks basic human social skills, growls when threatened, and eats with animalistic intensity.

The narrative is framed through the recollections of an elderly woman, (played in the present by Lee Young-ran and in the past by Park Bo-young), who returns to a rural cottage she lived in 47 years prior.

Imagine Let the Right One In , but with fur instead of fangs. A story where the scariest thing isn't the transformation—it’s the boy’s realization that the humans he loves are far more monstrous than he will ever be.

The story unfolds as an elderly woman named Sun-yi returns to a country cottage she visited in her youth. The narrative flashes back to the 1960s, where a young, sickly Sun-yi discovers a feral boy hiding in their yard. He cannot speak, behaves like a wild animal, and possesses a body temperature of 46 degrees Celsius.

Unlike Western werewolves whose transformations are often fueled by rage or curses, Chul-soo’s lycanthropy is a symbol of absolute, untamed loyalty. The film brilliantly flips the "Beauty and the Beast" dynamic. Sun-yi does not change Chul-soo into a human; rather, she gives his feral existence purpose. Performance and Practical Acting
