After being betrayed by the woman he loved for nine years, Lee Min-young swore that he would never love again. At 34 years old, he left behind the harsh life in Seoul and returned to his hometown. One day, an unexpected person appeared before him. Kim Hee-soo, a classmate from high school. When Min-young first saw Hee-soo, he couldn't remember her. He thought she was just one of many classmates. However, as their chance encounters continued, Min-young began to feel a strange familiarity and recalled a child from his past that he had tried to forget in Hee-soo's gaze. "It was you, it was you." The face he had desperately tried to erase from his memory, that was you. The irritation of Tae-yeon, who had hated the gaze that unconsciously watched you, was precisely you. That child from those days he had tried to ignore for Tae-yeon, that was you. Waves of uncontrollable love began to stir in Min-young's heart again, and his feelings for Hee-soo, who would become someone else's woman, grew stronger each day.
