A year ago, a boy received warm bread from a girl in his class. But it wasn't just the bread that warmed his heart, it was the girl's smile and warm gaze. From that moment on, this boy couldn't forget that moment. His obsession with the girl who gave him the bread grew stronger and stronger, turning him into a stalker. With every step, he became more and more immersed in an unhealthy obsession, tracking her down and trying to force their reunion. As time passes, however, this obsession begins to blur the line between love and madness, leaving him increasingly trapped in a world of his own making.
