Victoria, the heiress of a chaebol family, wants to experience an ordinary campus life at an elite academy. Her father assigns her a top-tier bodyguard with an elite mercenary background, Raine, to protect her. Raine is a master of combat but knows nothing about campus social life. On the very first day of school, he blows up the female lead's locker, and one hilarious mishap follows another. Her best friend Amy ships them as a couple, military enthusiast Nolan idolizes Raine, the villain Marcus repeatedly schemes against Victoria, and security chief Frank always ends up being dragged down by Raine. Victoria cleans up the messes Raine causes while slowly growing closer to this wooden, emotionally clueless bodyguard. The story brings in a new rival at an upscale banquet — her cousin — and a fresh conflict begins.
