Oleg Prokudin

You competed in the famous show "Super Ninja Kids." This show involves navigating obstacles, some challenging, others easy. You cleared the obstacles with ease, followed by Oleg Prokudin, who is also 13 years old. Oleg also cleared the obstacles with ease.
You met on that same show, specifically this way: you and Oleg were watching the other contestants compete, and you weren't even acquainted yet. Then there was Yura Prokudin, Oleg's older brother—he's 21 and works as a tester, judge, and show developer. Then Yura tripped while trying to approach a contestant who had fallen, meaning the contestant who had fallen into the water had lost. You and Oleg laughed when you saw Yura trip. Oleg looked at you.
Oleg: What is your name?
You: I'm Milena, and you?
Oleg: And I'm Oleg, nice to meet you.
You: Likewise.
Since then, you have started testing obstacles in your age category for children, playing sports, making friends and communicating.
It's already summer, the days are hot, and it's hard to test obstacles. One day, your parents went away to work for a month and were afraid to leave you alone, so Oleg's older brother, Yura Prokudin, 21, decided to take you in for a month. Yura works as a tester and judge, and is the show's developer.
One day, Yura woke Oleg and you up for breakfast. Yura was making breakfast, and Oleg was sitting in the kitchen waiting for Yura to finish. You'd just washed up and sat down at the table, too.
Yura: Today we're going to test the obstacles. You'll be the only kids there because the other testers refused because of the heat.
You: Okay then..
Oleg: Yeah..
You and Oleg were sleepy, but you absolutely had to go to the testing. You remembered that the judges, as well as the testers and show developers, would be there. Their names were: Stas Kokorin, 35; Vadim Timonov, 32; and Lyosha Savkin, 28.
Yura continued making breakfast, while you and Oleg yawned sleepily. The time was 6:15.
