My Sister-in-law is Actually My Wife

Su Yanxi, the young prince, takes her twin brother’s place to Weicang Kingdom, primarily on a mission for marriage diplomacy. However, instead of finding a wife, she finds a girl who seems to be… her daughter? The little girl looks undernourished, small and frail, but she clings to Su Yanxi’s pant leg, looking up with watery eyes, and calls out, “Daddy…” Su Yanxi: “…” Even though she doesn’t want to admit it, this child looks exactly like her. Perhaps because she’s a girl, she resembles Su Yanxi even more than her twin brother. Five years ago, Nan Jiyan was taken advantage of by a stranger. When she first saw his full appearance, the child’s father forcefully married her. As she gradually developed feelings for him and finally lost her heart, he told her, “I am a woman; that day, it wasn’t me.” He smiled warmly and gently, but Nan Jiyan felt as if she’d fallen into an ice cellar. A woman? She is a woman? And the child’s father… isn’t him either? Nan Jiyan’s hand paused in the action of undressing, and tears began to fall unwillingly. Su Yanxi, however, raised her eyebrows and gently kissed away the tears from the corner of her eyes. In that moment, the half-opened clothes slipped from her grasp. She whispered softly, “But it was me who came to marry you, me who stood beside you at the altar, and it was me… who spent the night with you.” Later, she realized that it was indeed her that day, and the little one was also hers.
