Su Qingyan, the legitimate daughter of the Prime Minister's Palace, was both talented and beautiful. She had been engaged to Prince Jing Xiao Jue since she was a child. She was a God-given match that was envied by everyone in the capital. However, on the eve of the wedding, Su Qingyan accidentally fell off a horse and was seriously injured. She was bedridden. The wedding was about to happen. The Prime Minister's Mansion was afraid of offending the imperial power, and was afraid of missing out on the marriage with Prince Jing's Mansion. In desperation, he pushed the orphan Su Wanqing, who was fostered in the mansion, into a substitute marriage.
