Lu Chuan, a master from Qinglan Mountain, descends the mountain solely to tear up his engagement and regain his freedom, but is splashed all over with muddy water by the luxury car of beautiful CEO Shen Qinghe, and accidentally saves her as she is hunted down by enemies. To his astonishment, the fiancée whose engagement he wants to cancel is none other than Shen Qinghe. Shen's family is deeply trapped in a deadlocked business war; to protect her own safety, Shen Qinghe hires Lu Chuan as her personal bodyguard. The two become bound together, joining forces to smash the layers of conspiracy by the He and Pei families, uncover the 15-year-old Qinglan Mountain secret and the truth behind Shen's father's murder, and clarify the mystery of Lu Chuan's parents' disappearance. Accompanying each other through mutual bickering and two-way protection, Lu Chuan tears up the old-style engagement, confesses with all his heart, and rushes toward the rest of his life with Shen Qinghe.
