What happened in the past and who has been there need to be slowly restored through scattered traces.The uneasiness caused by the case began to spread to the school and the community, and people who were originally unrelated to each other had to re-examine their relationships.

Jiang Ting's situation in the recitation team did not become easier because of the teacher's approval.The new opportunity made her more visible and brought her directly into contact with peer pressure.She began to understand that Su Lin's silence was not weakness, but a kind of self-protection in the absence of support.This realization led to a change in her attitude towards the disappearance.

As new clues emerge, the disappearance is no longer just about the whereabouts of a girl.Several families, several campus relationships and the choices of different people are all involved.Everyone wants to prove that they have nothing to do with Su Lin's experience, but the more they avoid it, the more clearly the harm hidden in daily life becomes apparent.
