Oksana is the director of an elite gymnasium. Controlled, unflappable professional—everything is under control. That is, it was—exactly until Liliečka Veselaya got enrolled. A little girl who melted her heart and… set the school on fire. And something went wrong at once. Instead of giving a proper talking-to to the angelic demon brat’s father, Oksana melts under the confident, scorching gaze of a former special forces soldier. And in the gymnasium, things begin to happen that are worse than a fire.
