When I turn 20, my grandfather's old friend—now the richest man in the country—lays out photos of his grandsons in front of me. He says, "Pick one to be your husband." Without hesitation, I choose Nathaniel Chapman. Everyone in the room is stunned. After all, it's no secret I've always been hopelessly in love with George Chapman. I used to swear I'd marry no one but him. In my previous life, I got what I wanted—I married George. And because of that marriage, he inherited the lion's share of his grandfather's wealth. But after the wedding, he started an affair with my sister. My parents were furious and sent her abroad to study. George thought I was the one who exposed them. From then on, he hated me to my very core. Women came and went at his side, each one resembling my sister more than the last. The betrayal crushed me. I fell into deep depression. Later, he secretly replaced my medication with slow-acting poison. I died with a child in my womb—alone, bitter, and betrayed. Now, I've been reborn. This time, I choose to let them have each other. But what I don't expect is that George has been reborn too.
