Nie Shuman, a freshman girl in high school, is used to living on the edge of tranquility, using her excellent grades to cover up her inner storm. She didn't expect that Zhou Yu, who transferred from Beijing, would enter her loneliness so naturally. The umbrella he handed over, the hot milk left on her table, and the words "it's better to face it than to escape", all fell exactly at the moment when she needed to be seen the most.
However, unexplainable cracks began to appear in the peaceful campus life. Nie Shuman's frequent nightmares, Zhou Yu's overly precise insight, and the almost resonant tacit understanding between the two all point to some kind of connection beyond common sense. When the class went to the forest park for an autumn outing, as night fell, the whispers coming from the ancient trees were exactly the same as the sounds in Nie Shuman's head when she had insomnia.
Zhou Yu is guarding her, and his gentle guidance hides an unquestionable possession. He said softly: "Don't be afraid, that's not your hallucination." Nie Shuman gradually discovered that the echo in the abyss of her heart might never be a one-man show. And she must uncover the truth: is it the abyss of mental illness, or the call of an older being awakening?
When the gaze becomes two-way and the echo has a source, they will face a world that subverts their cognition.
Intention: When there is an echo from the abyss of the heart, there is someone listening on the other side.
