Meng Xiaotang kindly gave a red string to Song Yunchuan in their childhood, unexpectedly causing a huge disaster. This matter spread all over the capital, and the two forged a youthful entanglement from then on. Years later, Song Yunchuan returned from military campaigns, looking handsome and graceful yet holding grudges everywhere and teasing Meng Xiaotang. Meng Xiaotang was forced into marriage by the profligate Li family young master, and in her haste proposed that Song Yunchuan marry her. Coinciding with the new emperor bestowing a marriage, the two got married. On the wedding night, Song Yunchuan dug up old accounts. From then on, the husband and wife guarded each other sweetly, joined hands to quell the Li family rebellion, welcomed the child belonging to the two of them, and had a fun side story of staying up all night copying scriptures to make up for it.
