When my five-year-old came home from a weekend at my sister Lily’s, he blurted out, “Guess what me and my other dad did!” I laughed—until I realized he wasn’t pretending. And when I learned Lily was in on it, my world tilted.Lily has always been my rock. After Eli was born, she showed up in the middle of the night with soup, cradled him through fevers, and gave me weekends to breathe. It became our rhythm: every Saturday, she’d whisk him off for adventures.

But that day, his innocent words made my heart pound. Eli had never known his real father—Trent left before I knew I was pregnant. I never told him. So who was this “other dad”?When Eli confirmed Lily knew him, I followed them the next weekend. At the park, I saw them—Lily, Eli, and a man in a cap and sunglasses, laughing like a perfect family. My stomach twisted.

Hours later, when they returned, I was waiting. And then I saw his face. Trent. Older, leaner—but him. Lily admitted she’d told Trent about Eli. He claimed he never knew I was pregnant. He just wanted to know his son. She thought she was protecting us, easing him into Eli’s life slowly.
