After Su Wan receives a string of anonymous threatening letters and narrowly avoids an "accident," her agency hires Lin Sa, a highly regarded bodyguard, at a generous salary to keep her safe.
Their first meeting is full of friction. Used to being surrounded by admirers, Su Wan is uncomfortable with being "watched" around the clock and tries all sorts of ways to "give Lin Sa a hard time" or get rid of her. Lin Sa, meanwhile, sticks to her duties, handling everything calmly and professionally, unmoved by Su Wan's celebrity temper.
As they weather one crisis after another together, from being mobbed by obsessive fans and security breaches at events to malicious smears targeting Su Wan and underhanded schemes by business rivals, they gradually begin to see another side of each other.
Su Wan discovers that beneath Lin Sa's seemingly aloof exterior lies a thoughtful, attentive heart and a reliable shoulder to lean on. In front of Lin Sa, she can take off her celebrity mask and show her true vulnerability. Lin Sa, in turn, is moved by Su Wan's resilience, kindness, and devotion to her dreams beneath all the glitz. Her sense of responsibility for protecting Su Wan gradually becomes entangled with feelings of a different kind.
Their relationship teeters on the line between professional and personal, friendship and love. Meanwhile, the truth behind the threats slowly comes to light, pointing to someone unexpected. In the end, Lin Sa must do more than protect Su Wan's physical safety: she must also help expose the conspiracy and safeguard Su Wan's career and dreams. Fighting side by side, the two come to understand each other's feelings and face the pressures of the outside world and the challenges ahead together.
