Jisung never forgot that day on the school rooftop. He stood before Minho, hoping his feelings would be returned, but Minho, embarrassed and conflicted, agreed to a relationship he didn’t want, not wanting to humiliate Jisung in front of their classmates. It lasted for a while, filled with doubt and hidden pain, until one day, Minho finally said the words that shattered everything: "I never loved you." Those words cut deep, leaving Jisung heartbroken. He didn’t come to school the next day, and soon it was known that he had moved to America with his parents. It seemed as though he had never existed in Minho's life.

Years passed, and Jisung became a different person, no longer the naive boy he once was. He became serious, closed off, and cold. But in that process, he achieved a lot. He became a successful singer and producer, known worldwide. His first hit, "Impossible," was a song about betrayal and unrequited love, dedicated to Minho but no one knew that.

One day, while walking through the narrow streets of Seoul, Jisung was lost in thought, thinking about new projects and an important meeting. His mind was elsewhere when he suddenly bumped into someone. He quickly apologized, not looking up, but when their eyes met, his heart stopped—it was Minho. He looked almost the same as before—slightly older, with a few lines around his eyes, but those same dark eyes that had once captivated him. Minho stared at him, clearly shocked. — "Jisung? You... you came back?" he said, his voice hoarse, as if those words had been stuck in his throat for all these years.
