After Becoming My Brother-in-Law's Replacement Bride

Yin Huai, heir to the Marquis of Wu'an, was young and accomplished. At just twenty, he led his troops to rout the enemy a thousand miles away and beheaded tens of thousands. The world was stunned and called him the "God of Slaughter."

When Yin Huai came of age to marry, the marquis's household arranged a match with the eldest daughter of a duke's family. The matchmaker said she was strikingly beautiful, virtuous, and the perfect wife.

But on the eve of the wedding, the young lady ran away with someone, frightened by his reputation.

Fearing the emperor's displeasure, the duke married off Xu Zhiyue, the second branch of the family, the next day. He came to apologize in person, asking the heir to secretly switch the sisters back once the eldest daughter had been found. He even swore to heaven that she was kindhearted and would never do anything to betray the heir.

Yin Huai regarded him with mockery and said, "Fine."

When he returned to the bridal chamber and saw Xu Zhiyue sitting on the wedding bed, so beautiful she seemed to drip with allure, he pulled back the covers and pushed her straight down onto the bed.

Xu Zhiyue had lived in her cousin's shadow since childhood. All she wanted was for the duke's family to divide up their household soon, so she and her cousin would no longer have conflicting interests.

Who could have guessed that one day she would be forced to marry the man her cousin was meant to wed?

Her uncle told her it was only a temporary arrangement. Once her cousin returned, they would switch them back.

But no one told her this was only the duke's wishful thinking. The Marquis of Wu'an's heir had never planned to switch her back in the first place.

One day, after finally seeing his true colors, she gathered her things and prepared to return to the duke's family. Yin Huai rushed back, sent the servants out of the room, wrapped an arm around her waist, and coaxed her softly: "Don't go, all right?"

"Liar. So you never wanted to marry my cousin at all."

Yin Huai kissed her face, making no effort to hide his possessiveness. "That's right. You were always the only one I wanted to marry. If you don't want me to go mad, then be good and do as I say. Otherwise, I'll tie you up. Understand?"

Xu Zhiyue was at a loss whether to laugh or cry.
