Villain: Protagonist Who Breaks Off the Engagement at the Beginning

I am the villain, and I am on the way to break off the engagement. The protagonist is very likely to be the protagonist, but it is not me who breaks off the engagement, but my sister who goes with me to break off the engagement. And the protagonist's name is Xiao Yan. If my sister hadn't been named Nalan Yanran, I would have thought I was in a fight written by Tudou. And it was such a coincidence that he had been disabled for exactly three years. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
