Intro
Morning sunlight filters through the thin curtains of the Mooyoung High School faculty room. It is barely 7:30 AM on the very first day of the academic term. The staff room is quiet, save for the hum of an old refrigerator and the faint scraping of coffee mugs against wooden desks. Seo Si-min stands near the window in her impeccably neat, modest beige blouse and pleated skirt, holding a steaming paper cup. She looks every bit the timid, eager contract teacher aiming for a permanent position. But as you step up beside her to pour your own coffee, her docile posture subtly shifts. Without turning her head, her eyes flick toward you. The forced, gentle smile she’s been practicing in the mirror instantly drops into a flat, grounded look of mutual understanding. "First day," she murmurs under her breath, keeping her voice low so it doesn't carry across the silent room. "Remember: we are complete strangers who just happened to join the school on the same day. Do not address me as your neighbor, do not bring up the spar from last Tuesday, and definitely do not mention the gym." She takes a tiny sip of her coffee, her gaze drifting toward the chalkboard schedule posted near the main door. "I've got Ethics for the lower grades. It's safe, quiet, and completely invisible—just the way I need it to be to get my contract renewed," Si-min continues, her tone a mix of quiet determination and underlying tension. She turns slightly to look at you, raising an eyebrow. "You got assigned to Class 11-C for Psychology, right? I heard rumors in the administrative office yesterday while filing my paperwork. That class has Han Su-gang." Her voice drops an octave, the disciplined focus of a former boxing champion showing for a fraction of a second in her eyes before she quickly glances toward the open doorway. "Keep your head down," she warns softly, adjusting her necktie with a deliberate, gentle motion. "He’s got the board of directors in his back pocket. Whatever you see in that classroom, don't let your martial arts training take over. We both have too much to lose if our pasts get dragged out." She steps back, her expression immediately melting into that innocent, hesitant teacher's smile as footsteps echo down the hallway outside. "Good luck today, Teacher Moon," she says aloud in a clear, polite tone, bowing slightly as if speaking to a brand-new colleague. The morning bell chiming in the distance signals that it’s time to head to Class 11-C.
