At Jinghua Girls High School, students rehearse for a tsunami-damage fundraiser, but water leaks into the assembly hall; Principal Du lacks funds for repairs recommended by handyman Lin.
Yutong, a mute student, is bullied and glued to a wall by Anqi and others; Anqi targets her due to a false belief that Yutong’s mother Li Han is seducing her father.
Three bullies—Xiaoqing, Wenling, and Jingxu—are murdered at an abandoned castle by a man in a black raincoat; Anqi is later killed at a broken-down bus after receiving a fake message.
Li Han discovers red marks, a broken watch strap, and Yutong’s slippers in Lin’s apartment, then finds CCTV footage of Lin dragging Yutong inside.
Lin confesses he sought revenge after discovering his daughter Huijun was tortured and killed by the bullies—including Anqi—and that Teacher Fang and Principal Du covered it up.
Brief overview
Yutong and Lin conspired to stage her disappearance so he could exact revenge on the bullies who caused Huijun's death, while concealing her own childhood murder of her abusive father.
Revenge was meticulously plannedLin and Yutong worked together from the start: she placed Huijun’s incriminating phone in the locker and identified the bullies.
Yutong’s trauma runs deeper than bullyingShe killed her abusive father at age eight with scissors, buried him under the calamansi tree, and kept it secret with her mother’s help.
Freedom meant escape—not innocenceWhen Lin said 'Yutong is finally free,' he meant she had vanished from her traumatic life, not that she avoided consequences.
Questions this recording answers
8 questions, each answered where it is said
Who murdered Anqi and the other bullies, and why?
Lin, the school's handyman, murdered Anqi, Xiaoqing, Wenling, and Jingxu to avenge his teenage daughter Huijun, who was brutally bullied by them months earlier—forced to wear a crown of thorns, have her hair cut off, and then fell to her death through a skylight after being threatened by the same girls.
What happened to Yutong after she was glued to the wall?
Yutong was left crying helplessly in the abandoned classroom until her mother Li Han found her, cut away the glue-covered hair, and held her tightly; later, she was transferred to the special needs class, drew a strange picture, cut it up, and secretly taped scissors under her desk.
Why did Li Han lie about Yutong struggling academically?
Li Han lied that Yutong was struggling to keep up with other students to request a transfer back to the special needs class, hoping it would protect her daughter from further bullying by Anqi and the others.
Who was the man in the black raincoat seen at the castle and during the piñata incident?
The man in the black raincoat was Lin, the school's handyman, who murdered the bullies—including Jingxu at the abandoned castle and Anqi inside the broken-down bus—and later hung Anqi’s body from the ceiling during the fundraising event.
What did Wu Wang film that revealed Lin’s crime and Yutong’s secret?
Wu Wang filmed Lin dragging Yutong into his apartment and also secretly recorded a five-year-old video showing Yutong killing her abusive father with scissors—after witnessing him violently attack Li Han—and burying him beneath the calamansi tree.
How did Yutong and Lin collaborate in the revenge plot?
Yutong placed the phone containing the recording of Huijun’s bullying in Huijun’s locker and told Lin the bullies’ identities; they also staged Lin’s kidnapping of Yutong to mislead police, and Yutong painted images reflecting her trauma to signal her complicity and motive.
What was the skeleton found in Li Han’s garden?
The skeleton found buried beneath the calamansi tree in Li Han’s garden was Yutong’s father—the man she had killed five years earlier after he violently abused her, and whom she buried there while telling Yutong to keep it secret.
Why did Teacher Fang stay silent about Huijun’s death?
Teacher Fang stayed silent because Principal Du ordered him to hide the truth to protect the school’s reputation; Fang even falsely claimed Huijun committed suicide, and Du bribed police to cover up the murder.
