Your Letter follows the story of Lee Sori, a polite and righteous girl who decided to stand up for her bullied friend, Kim Julie. Unfortunately, this action backfired on Sori as the bullies switched their target to her.

Soon after, Sori returns to the city she used to live in, hoping that transferring schools will help her escape the hopeless situation. However, Sori's traumatizing experiences saw her alienate herself in the new school. That's when she found a mysterious letter taped under her desk.

While its contents were intriguing, they also led her to another letter, launching Sori on a scavenger hunt to find the true purpose of the letters and the anonymous person behind them.
