Ten years ago, when down-on-his-luck youth Gu Xuanchuan was in his hardest times, he received a steamed bun from Shen Qingyao, and from then on remembered that kindness. Ten years later, having completed his studies, he returns and walks into the Shen family's bride-choosing banquet, publicly choosing Shen Qingyao, who is mocked by all due to scars on her face. Facing guests' humiliation, peers' provocation, and the martial arts gym's decline, he uses medical skills to heal her wounds and national martial arts to guard the Shen family's dignity. Shen Qingyao bravely raises her head again, working together with her father and disciples to revitalize the martial arts gym. From guarding each other to settling down together as a family, the two make the quieted plaque light up once more, and let more children understand that learning boxing means learning etiquette first, and practicing martial arts means becoming a person first.
