She is the legitimate daughter of the Shen family, and he is the concubine-born son of the Qi family who married into it. Carefully cultivated, a few days before the imperial exams she tied a red string for him, and he said, "This life is tied by my wife." Later, the Shen family was raided, she was exiled to Bashu, and he placed high in the imperial examination as top scholar. Thinking she was dead, he searched like a madman for three years, until they reunited at the ferry pier. She stood in the rain holding an umbrella, as if the love of their youth had returned to his side. Later, he cleared her name, beat the grievance drum, and knelt at the palace gates. All along the way they searched for the affection belonging to their youth; she opened a bookstore, and he came to pick her up to go home after court. The return journey was long, and they walked for a long time. Fortunately, they finally reached each other's side.
