Cai Yu was born with jade-like bones and a supple waist, her beauty like a begonia; the Crown Prince took a fancy to her and sent her to the Yan Prince's mansion to tempt the Yan Prince into breaking his vows. 　　Song Yinghuai was radiant and serene, like clear skies and a gentle breeze. Rumor had it that after being beaten in love, he voluntarily sought refuge in the Buddhist order, practicing asceticism and indifference to the extreme. 　　To save her family, Cai Yu used every trick in her arsenal. 　　Facing the beauty sent by the Crown Prince, Song Yinghuai's long, powerful fingers twirled the prayer beads in his palm inch by inch. He pushed away Cai Yu's hand and said lightly, "Mind the separation between men and women." 　　Cai Yu's eyes flickered, she curled her lips in a smile, and with a pale hand she stroked his feverish chest. "Is it that your maid disregards the boundary between men and women, or that Your Grace's Buddhist heart is unsteady and harbors tender thoughts?" 　　Song Yinghuai's robes did not stir, yet the wind would not cease. 　　Cai Yu hooked a finger around the beads at his neck, her voice softer and more beguiling than ever: 　　"Prince, give me your heart, and the Buddha will be yours. How about that?" 　　Cai Yu kept on tempting him, but unwittingly she paid with her own heart. 　　Only when the news came that he had killed her entire family did Cai Yu's pain pierce to her core and she suddenly wake to the truth. 　　It turned out Song Yinghuai had only ever treated her as a forbidden plaything. 　　She finally faked her death and withdrew, but Song Yinghuai crushed his prayer beads, pining for her, breaking his heart and corroding his soul. 　　Later, when he heard that she had agreed to marry the Jizhou garrison commander, the ever-abstinent Song Yinghuai's eyes darkened; for the first time in his life he abandoned his restraints and committed all manner of transgressive acts.
