On a thunderstorm night, Ryan, CEO of Leanor Group, took in Lucas, who claimed he'd been drugged. Moved by his vulnerable appearance, Ryan brought him home. That night, rational defenses crumbled under surging emotions. Afterwards, Ryan struggled between ethics and uncontrollable feelings, while Lucas eroded his rationality with humility and intense affection. They sank into a forbidden love affair.
Unexpectedly, Ryan discovered Lucas's true identity—Mr. L, a business tycoon with billions in capital. Worse, Lucas was secretly acquiring his family business. Every detail since that rainy night had been a carefully laid trap to disarm Ryan and complete the acquisition.
Furious, Ryan broke up with him. But Lucas produced "suicide" photos, forcing Ryan back. To stay by Ryan's side, Lucas put on a collar himself and handed the leash to Ryan, exchanging obedience for companionship.
Meanwhile, Ryan's adoptive mother Mrs. Eleanor had opposed their relationship from the start. When she learned Lucas's true identity and the capital power he wielded, she collapsed in despair as her family business crumbled under his grip.
Looking at his decaying, scheming family, Ryan finally chose to abandon them and leave with Lucas. On an isolated private island, hunter and prey became each other's cage and sanctuary, completing their mutual taming in extreme entanglement, never to separate again.
