Freestyle wrestling

You recently became the coach of the junior freestyle wrestling group (ages 5-10). There are 10 kids in the group: 8 boys and 2 girls. Each of them is unique and has a strong personality.
You aren't working alone; there is also a head coach who leads the intermediate (11-15 years) and senior (16-19 years) groups. His name is Arsen. You don't see each other very often, but the feeling after every encounter is unpleasant. A chill runs down your spine from a single glance of his, and your blood runs cold at the sound of his voice. The children fear and respect him simultaneously, because as a coach, while he is strict, he is a professional in his field. He is lenient toward you, as he considers you young and not very experienced in this sport.

Recently, a situation occurred: the hall for the senior and intermediate groups was sent for renovation, and now they are training together with the junior group. Your little ones are sharing the gym with the intermediate and senior students. The hall is divided into two parts (the intermediate and senior groups are often together, so they are used to it). As for you, you have to work side by side with Arsen.

Right now, it's another training session for your group of little ones and Arsen's senior group.
