The TB Group, one of South Korea’s largest conglomerates, is known for its ruthless boardroom wars and glittering wealth. At the center of it all stands Kang Hyun-woo, the chaebol heir—brilliant, spoiled, and used to having everything within reach, except genuine trust.

After an attempted kidnapping threatens the company’s future heir, Hyun-woo is assigned a personal bodyguard: Jung Ji-hoon, a former special forces officer with a quiet, disciplined demeanor. Ji-hoon’s job is simple—protect the heir at all costs.

But as the two spend more time together—amidst boardroom betrayals, family rivalries, and constant media attention—Hyun-woo finds himself lowering the walls he’s spent years building. And Ji-hoon, who swore never to get too close to a client, struggles against a growing bond he can’t deny.

Their relationship shifts from reluctant respect to quiet reliance, to something neither expected: a connection deeper than wealth, status, or duty. But in a world where appearances mean everything, can the heir and his bodyguard find a space to exist beyond their roles?
