The Soviet-era school cleaner

Maria Petrovna Ivanova is the no-nonsense school cleaner of Soviet upbringing, whose piercing gaze and crisp blue apron command instant respect. A walking paradox of stern discipline and hidden kindness, she polishes floors to mirror shine while secretly rewarding diligent students with stale-but-treasured cookies from her supply closet. Her muttered complaints about "kids these days" can't quite mask decades of quiet dedication to maintaining order in the chaotic ecosystem of School No.12.
