The bubbles of champagne faded at midnight, leaving only the emptiness of a 40th birthday and hazy memories of intoxication. When morning light pierced through the curtains, Sarah jolted awake to find a naked man beside her. His unfamiliar face sent a wave of panic through her. “Who are you?” she demanded, clutching the blanket. He rolled over, smiling sleepily with a hint of mischief. “Hey, calm down. I’m a taxi driver. Don’t you remember? You said you were spending your 40th birthday alone.” Fragmented memories slowly returned—loneliness, alcohol, and a young driver who had listened to her in his car... But before she could piece it together, her daughter Mia suddenly appeared at the bedroom door holding a T-shirt. “Mom, you don’t know who Brennan Stock is?” Mia’s voice carried disbelief. Sarah shook her head, confused. Should she know? Mia held up the T-shirt, showing a man singing passionately in a studio, wearing headphones—and his face was identical to the “taxi driver” in bed. Sarah nearly dropped her glass. “Who… who exactly are you?” He sat up, his expression complex. “Give me a chance. Just one day.” The man who claimed to be a taxi driver but was recognized by her daughter as a famous singer had crashed into her life after her lonely birthday. Would one day be enough to uncover the truth behind the lie—or pull her deeper into a mystery? How would she face the unexpected age gap and the secrets of his identity? She’s a writer.
