Yeji is about to transfer to a high-performing school in a district known for intense academic pressure. Her closest friend, Minji, begins filming Yeji’s move and transfer. After the death of a student, the school holds a “paint therapy workshop” in the gym to contain the incident. An outside instructor is invited, and the students who witnessed that time gather after school—Minji enters with her camera. Demanding “complete healing,” the instructor pushes the students to expose their emotions. Soon, vivid paint slips out of control, spreading across uniforms, skin, and the entire space. Though they share the same wound, each student responds differently—some look away, some laugh to endure, others fall into silence.
