Aiden, the successor to a legendary healer, descends from the mountains in search of his fiancée—known only by the nickname "Rainy" and a distinctive raindrop-shaped birthmark on her hip. Upon arriving in Xigang, a wild, impulsive night with a female CEO named Serena leads to him becoming her personal bodyguard. As he helps Serena fend off underworld threats and thwart schemes within her own family, Aiden discovers that her best friend, Vivian, bears the exact same birthmark and nickname. Could he have more than one fiancée? Wielding a lost, ancient technique involving silver needles, Aiden crushes every adversary in his path—yet he finds himself caught in a difficult predicament as the two beauties begin a "fair competition" for his affection. Ultimately, the conspiracies are dismantled.
