Toxic Parents

Yoo-ri, a model student from a privileged home, takes her own life, shattering her mother Hye-young's world. While detectives rule it a suicide, Hye-young is convinced her daughter's classmate Ye-na and homeroom teacher Gi-beom are murderers. Her relentless, grief-driven investigation peels back layers of adolescent secrets and schoolyard politics, where every testimony conflicts. As the police probe deeper, they uncover that the most profound fractures in Yoo-ri's heart were inflicted by Hye-young herself, a mother utterly blinded by the belief her smothering control was the purest form of love.
