Lin Chuan, an unemployed boxer, takes a job as the bodyguard of the cold and elegant CEO Su Wan to pay for his sister's medical bills. He has a "self-discipline system": he forces Su Wan to practice self-defense at 5 a.m., only allows her half-sugar coffee, and even brings her nutritious lunch to meetings, earning him the label of "too rigid". But when Su Wan faces a fatal assassination, Lin Chuan uses the fighting skills he practiced 10 hours a day for three months to block bullets, uses the system to warn of explosions, and helps her uncover the internal traitor. It's then that Su Wan discovers—this "too disciplined" bodyguard is the poor boy she saved years ago. To be worthy of her, he used the system to turn himself into a "perfect guardian", hiding a three-year crush that finally comes to light in a life-or-death moment.
