The chemistry between Vanessa and Adrian is clear, but the most interesting part is their second rule. They agreed not to fall in love, yet their conversation already hints at something deeper than a casual encounter. Sometimes, the feelings people try hardest to avoid are the ones that catch them off guard.

For 17 years, my father sent a birthday card to a little girl he had never met. Every year, he included $100, a handwritten letter, and the same sentence: “I’m sorry I couldn’t be there when you needed me.” I grew up thinking my father was the kindest man alive. He worked as a mechanic in Cleveland, Ohio, rarely complained, and somehow managed to make our small house feel like the safest place in the world. But there was one thing about him I never understood. Every November, a few days before his birthday, he’d sit at the kitchen table with a blue envelope, write a letter, and ask my mother to help him mail it. One year, when I was 15, I finally asked him who the girl was. He stopped writing. “Her name is Emily,” he said. “Is she your daughter?” My father put down his pen. “No, sweetheart. But I wish I’d known her when I had the chance.” I thought that was a strange answer, but he refused to explain further. Years passed. I went to college, graduated, and moved to Chicago for work. My father continued sending those cards, even after my mother died. He never missed a year. Then, when I was 26, my father suffered a stroke. He survived, but he struggled to speak and needed help with everyday tasks. I moved back to Cleveland temporarily to care for him. One afternoon, while sorting through his paperwork, I found a shoebox filled with copies of the letters he’d sent Emily. There were seventeen of them. The earliest was dated 2007. I opened the first letter. “Dear Emily, You don’t know me, and you have no reason to forgive me for something you don’t even remember. But today you turn five, and I hope someone makes you a cake, sings to you, and tells you how precious you are. I think about your mother often. I think about the day I was supposed to meet you, the day I promised I would come to the hospital, and the day I chose to be afraid instead. I cannot change what happened. I can only hope that one day you’ll understand that the worst mistake of my life wasn’t something I stopped caring about. It was something I cared about so much that I was too ashamed to face it.” I sat on the floor, reading the letter again. There were no photographs in the box, no explanation, and no address except a post office box in a neighboring town. I looked through the remaining letters. Some were cheerful. Others were heartbreaking. My father wrote about his work, my mother’s cooking, and the small joys of growing older. But every letter ended with the same apology. I needed to know who Emily was. And I needed to understand what my father had done that made him spend seventeen years apologizing to a little girl who might never even read his words.
