Convalescing in the mountains after the war, wounded veteran Seoyun rescues an abandoned young wolf shifter and names him Yeonho. Taking him in like a son, Seoyun slowly earns the distrustful boy’s devotion. But as Yeonho matures under his tender care, his adoration curdles into something far more intense than family or duty. One afternoon, Seoyun accidentally catches Yeonho in a moment of solitary pleasure – and the fragile boundary between guardian and ward shatters forever.
