Synopsis: Jiang Wan is a confident, well-liked teaching assistant until the day a student in the third row makes her chest tighten with a feeling she can’t place. He introduces himself as her old neighbor. She remembers who she was at fourteen: the girl who stole snacks from a smaller, quieter boy and made him cry. He was small then. He’s anything but now. As the past collides with the present, Jiang Wan must face the girl she used to be and figure out whether the man she wronged came back by accident, or on purpose.
