Seventeen-year-old Su Yehan's life is made up of three pieces: the belt left by his father, the blind eye of his mother, and the glimmer of light brought by psychiatrist Lu Chenyan.
Gu Yan is the only exception who enters her gray world. Across a desk, in late-night WeChat messages, and in face-to-face communication, they were raising a secret monster called "love".
She thought his gentleness was the moonlight that spread to all patients,
He thought her dependence was merely a necessary transference in despair.
A fatal misunderstanding quietly grew - she didn't know that that special concern only belonged to her; he didn't know that the silent girl's heart had already ignited passionate feelings.
Until her mother tore up the sketchbook where she hid her thoughts, until her father's harsh words crushed her last dignity. On the day when she counted the 99th meaningful sunset in her life, the girl chose to fall from the rooftop.
In her pocket was a letter that could never be sent.
In the letter, there is a truth that he will never know, and a grand, silent confession.
Later, Dr. Gu realized that her last cry for help was hidden in that sunset where no one responded.
Concept: A girl in the abyss of domestic violence and depression begins to fall in love during her communication with a psychiatrist. The fatal misunderstanding made her think that his tenderness was just a professional habit, while he did not dare to admit his heartbeat due to ethical constraints. In the end, the girl went to destruction under the pressure of her family, leaving only a letter of confession that he would never receive, revealing this two-way love that no one knew about and missed each other.
