Xu Wen seems like an ordinary office worker, but he possesses a mysterious golden finger: the ability to sense the “Celestial Maiden Mark” of the person destined for him. Forced into a family-arranged marriage, he weds Su Qingxue, a woman he has never met. At first, the two are strangers under the same roof. Xu Wen silently protects her with the unwavering loyalty of a devoted guard dog, never revealing how he feels.
His sharp-tongued mother-in-law makes life difficult for Su Qingxue at every turn, questioning her background and abilities and even driving a wedge between the couple. Xu Wen appears to endure it all in silence, but behind the scenes, he uses his golden finger to defuse one crisis after another and keep his wife safe. Su Qingxue gradually realizes that her quiet, taciturn husband always appears at crucial moments to shield her from harm.
From misunderstanding to understanding, from indifference to deep affection, Xu Wen’s dogged devotion and protection gradually melt Su Qingxue’s defenses. When the secret of his destined bride is revealed, the two finally understand that their marriage was no accident: it was a promise fate had written long ago. A marriage before love, followed by a love that never fails.
