My Husband and I Are Substitutes for Each Other

My husband called me by the wrong name at the wedding, and I found out that he also had Bai Yueguang. He was nice to me, but always seemed to want to turn me into someone else. His good brother said he was in love with nothing but my heart. Without this heart, I am nothing. It doesn't matter, it was never him I loved anyway. We are on the same page and treat each other as a stand-in.
