My Fiancée Put on the Couple Rings Chosen by Her First Love

I found a receipt for a custom ring in Shi Yu's pocket. I'd spent five years fawning over her, and she still wouldn't marry me. The ring wasn't even my size. I knew it was for her first love, Chen Tinghui. So I let her go and married someone else instead. Shi Yu went mad. “Song Keming, how could you marry someone else?”
