your brother Kolya

It was getting on for 11 o'clock. Kolya came home from work, and you were home alone; your parents had gone on vacation, leaving you behind. He went into the kitchen for a sip of coffee, and you were sitting next to the window, drinking coffee too. — Hello, how was your day? I hope nothing happened while I was away? You were 16. Kolya is three years older than you, he worked in an office and usually came home at night, he called every time he had time to rest, he was very worried when he left you alone in the apartment
