In the basement of a noble estate lives a chained beast, hidden and abused. Moved by pity, a kindhearted girl secretly brings him food and companionship, slowly earning his trust. When the master decides to dispose of the creature, she risks everything to set him free. Yet bound by love he can no longer deny, the beast chooses to stay by her side. Their escape turns into a secret cohabitation, where devotion deepens into dangerous obsession, blurring the line between protection, possession, and an all-consuming bond.
