The Plot

Former boxing champion So Si-min (portrayed by Shin Hae-sun) has traded the ring for the classroom, now working as a substitute teacher at a high school. Determined to secure a permanent position, she tries to keep a low profile, choosing to ignore the escalating violence and bullying erupting around her. Her silence isn’t born of indifference, but of a calculated effort to avoid any confrontation that might jeopardize her future.
But Si-min’s resolve begins to crack as she witnesses the unchecked cruelty of Han Su-gang (played by Lee Jun-young), a notoriously violent student who terrorizes his classmates with impunity. When his aggression targets her directly, she can no longer justify staying silent.
Faced with a choice between self-preservation and doing what’s right, Si-min decides to act. Donning a distinctive cat mask to conceal her identity, she channels the strength, skill, and spirit of her former self. Using her boxing prowess, she secretly takes on the toxic power dynamics that rule the school, becoming an anonymous force for justice.
What follows is a gripping battle, not just against physical threats, but against a broken system that has long enabled silence, fear, and abuse to thrive.
