On his wedding day, Lu Chengyuan was blackmailed by his fiancée Lin Wanwan with a last-minute price hike. Out of despair, he immediately married his business rival Jiang Yu'an instead. After marriage, he gradually discovered that Jiang Yu'an had silently loved and protected him for seven years, and she was also the person who saved him in a car accident back then. Lin Wanwan and Su Man refused to accept this and provoked them, but instead suffered a joint counterattack from the two. As the truth of the old case was unveiled, Lu Chengyuan let go of his emotional baggage and passionately pursued his wife, while Jiang Yu'an also transitioned from calm restraint to heartfelt response. Having weathered various trials, the two officially registered their marriage, turning an arranged marriage of convenience into a mutual journey toward each other.
