Since childhood, Jihyeok has harbored a deep, unrequited crush on his next-door neighbor, Taeseong, the gentle older man who stepped in to take care of him when his own indifferent parents wouldn't. Because Taeseong always carried himself with an air of pure, detached innocence, Jihyeok never even dared to touch him in his wildest fantasies, choosing instead to quietly harbor his feelings from afar.

That fragile restraint shatters in an instant when Jihyeok accidentally stumbles upon a dildo inside Taeseong's bag.

Realizing the saintly man he idolized actually hides his own secret, intensely dirty desires behind closed doors, a dark flip switches inside Jihyeok. The boundary between innocent affection and raw possessiveness dissolves, opening the door to an intoxicating, uncharted relationship.
