In "Duty After School" Episode 9, titled "The Truth Of The Matter is…," the
students face the grim reality of betrayal within their ranks, testing their
bonds and the very foundation of their trust. The episode opens with the
students evading the prisoners, a perilous game of cat and mouse where the
stakes are life and death.

The students' plan, a dangerous yet ingenious strategy, involves luring the spheres to attack the prisoners. Their decision to remove the bullets from their guns and pretend to surrender is a desperate move that showcases their resourcefulness under pressure. The element of surprise, when the spheres descend upon the unsuspecting prisoners, turns the tide in the students' favor.
The brutal outcome of the encounter leaves a lasting impact, with the last prisoner meeting a tragic end at the hands of his own comrade. The students' display of mercy towards the man who attempted to save them reflects their capacity for empathy, even in the face of treachery.
The rescue of Ae-seol is a pivotal moment, with Bo-Ra's courageous act revealing her true feelings for her friend. The students' triumphant return to the base, armed and ready to confront the challenges ahead, is a testament to their resilience.
Back at the hospital, the somber mood surrounding Soo-chul's body brings a sense of gravity to the students' mission. The discovery of the rigged votes and the ensuing confrontation expose the deep-seated betrayal within the group. The revelation that Soo-chul, along with Yoo-Jung, Jang-soo, and Kwon Il-Ha, manipulated the elections and sabotaged the radio for the perceived safety of the group ignites anger and resentment.
The accusation and the heated argument that follows force the truth to the surface, leaving the group to grapple with the reality that they have been coerced into a war they did not choose. The apology from the guilty quartet and their justification for their actions do little to quell the fury of their peers.
The emotional turmoil is palpable as the students come to terms with their forced participation in the conflict. The collective decision to return to Seoul, despite Yoo-Jung's warning of the dangers, signifies their desire to reclaim their agency and return to their homes.
Chi-yeol's promise to Na-Ra to search for their parents in Seoul and his contemplation over Soo-chul's mysterious death add a layer of complexity to the narrative. The advice to wait for concrete evidence before taking action underscores the need for patience and wisdom in their pursuit of justice.
The episode concludes with the students' departure for Seoul, a journey fraught with uncertainty and the hope for a better future. The narration reflects on the transformation they have undergone since the war began, a poignant reminder of the irreversible changes in their lives.
"Betrayal and Redemption" captures the essence of Episode 9, a story of treachery, truth, and the quest for autonomy in a world turned upside down. The students' journey is a testament to their strength and the enduring power of unity in the face of adversity.
