My Fiancé Gave the Polo Championship to His Concubine’s Sister. After I Married Someone Else, He Went Crazy with Regret

The pearl-and-jade hairpin my late mother lost turned up as a prize at a polo match in the capital. My childhood sweetheart promised he would take first place and win it back for me. But he broke his promise. He deliberately lost to the heir of the Marquis of Dingbei, just to get the prize for second place: a flowing fairy dress. It was the dress my half sister had wanted for a long time. My childhood sweetheart said helplessly, with indulgent affection, “Ying is about to come of age. This is the only dress she wants, and I promised I’d give it to her.” Wearing the flowing fairy dress, my half sister said smugly, her voice sweet and charming, “Elder Sister, isn’t it unlucky to keep something that belonged to a dead person?” My childhood sweetheart tried to comfort me. “When I come to ask for your hand, I’ll have Baibao Pavilion make you an identical hairpin. Would that do? It’ll be even prettier than your birth mother’s.” Too late. My mother had said while she was alive that she would marry me to whoever offered the hairpin as a betrothal gift. In three days, I would be the wife of the heir to the Marquis of Dingbei.
