How Humble Would It Be to Marry Someone Who Doesn't Like You?

I knew that Gu Yu only liked Sister A, but I still forced him to marry me. I became his crown princess as I wished, and my sister also married Xu Ruosheng as she wished. The day my sister died, he grabbed my neck and yelled, "Why wasn't you the one who died?" I became the culprit who killed my sister, and I lived in regret every day. Later, Gu Yu brought someone back from Jiangnan. It turns out that everything is false, only the deep-seated hatred is real.
