During a dinner party, an old man was suddenly asked who he'd talk to if he'd die soon. Out of nowhere, the high school girl he deeply loved and even had a daughter with at a tender age popped into his mind. At this point, 50 years had passed since their reluctant separation. How was his sweetheart now? Where was their never-seen daughter? Instinctively, the man decided he wanted to find them, but he had never expected things would develop out of control.
