A Beggar Applied to Be a CEO's Bodyguard—She Mocked Him, Unaware He Was a War God Who Beat Everyone!

After years away, a mysterious man returns to protect a young female CEO. During a routine security inspection, officers discover battlefield scars and a record of extraordinary commendations—yet he jokes through the encounter as if nothing matters. At a seaside restaurant, the CEO finally meets the man chosen by her family, and their first exchange is anything but romantic. She sees an arrogant flirt; he sees a woman surrounded by danger. When attacks begin, the threat leads back to a powerful business family determined to seize her company’s anti-cancer project. An insider, a compromised security network, and a ruthless corporate heir push the city into a high-stakes power struggle. The supposed bodyguard keeps turning impossible situations into teasing reversals, while a top-ranked international female opponent enters the game and hidden loyalties surface. As the CEO’s resistance begins to crack, one question grows louder: who is this untraceable man—and why does every major force in the city fear him?
