For Jaeyun, the marriage is a nightmare-a forced union with a man whose piercing gaze feels like a cage. But for Heeseung, Jaeyun is more than a husband; he's an obsession, a fragile beauty Heeseung is determined to protect, control, and claim as his own. Theirs is not a marriage of love but a battleground of willpower and emotions, where every encounter reveals more than either intended.

Despite his resistance, Jaeyun can't ignore the magnetic pull between them, leaving him caught between fear and an unspoken yearning. As they navigate their tangled emotions, dark pasts, and unexpected connections, their marriage evolves into something neither of them expected.
