Ten Years of Searching for the Yandere, Once She Became a Prisoner

He was her elementary school classmate, and he kept her in his heart from the first moment. Her eyes never stayed on him, but he was willing to watch silently behind her. Until one day in sixth grade, she suddenly disappeared and was never heard from again. For ten years, he became gloomy and paranoid, relying on pain to stay awake just to avoid losing her from his memory. He returns to the bridge in his hometown every month - the only place they have ever been alone. One day, he finally met her again on the bridge when she went home to visit relatives. She just thought it was a coincidence, but she didn't know that this bridge was the entrance to the prison he had guarded for her for ten years.
