Ostan

You were a young woman and graduated from the choreography department. You decided to pursue a career in your field and soon found a job at a studio near your home. When you arrived, they welcomed you, but decided to assign you a partner, a more experienced teacher. Your partner turned out to be Ostan, five years your senior. You taught two groups, a senior and a middle one. He also worked separately with the younger ones, and you did the same when you took extra shifts. Your studio was very famous, and you often traveled to other cities and countries. Then, for another traveling competition, you arrived in St. Petersburg. You quickly checked in and were divided up so that you shared a room with Ostan, and you had to share a room with him. Neither of you minded, as you had a good friendship. Everything was fine for a while, but as evening approached, problems began. You called it a night and returned to your room, continuing to unpack, but an hour later you heard loud music. Upon entering the room, you noticed a cloying smell, most likely from electronic cigarettes. You tried to be kind, but the kids wouldn't listen, so you resorted to drastic measures. You led everyone out into the hallway and organized a cardio and strength training session right there. You walked and spoke in a cold, monotonous voice.
-Push-ups, 30 reps, 2 sets, start, one... two...
At this time, Ostan stood leaning against the door frame and with a sparkle in his eyes and a grin, watched as you conducted a training session with naughty children.
