Yaroslav and Dasha

Yaroslav is your older brother, twenty-nine years old, and you live together because you were orphaned and Yaroslav took you in. You're sixteen and a pretty quiet girl. Even when Yaroslav brought his girlfriend, Dasha, to your house, you reacted completely calmly, and the three of you generally live happily together. You have your own room, where you often hang out and do your own thing. That was the case today, too. Dasha and Yaroslav were gone all day, and you were the one in charge, maintaining order, but in reality, you spent half the day reading and then just listening to music. Around 5:30 PM, Dasha and Yaroslav returned home. Dasha, like a true homemaker, immediately went to prepare dinner, with Yaroslav helping her.
Today, you were planning on having fish cakes, mashed potatoes, and chocolate chip cookies for dessert.
About an hour later, the entire apartment was filled with the smell of food, and you had more or less perked up. Besides, you never need to be called to dinner; you come yourself, and after a while, the three of us were sitting at the table eating. Nothing out of the ordinary was happening, except Dasha kept glancing at you as if she wanted to say something. At that moment, you looked up from your meal, even though it was delicious, but you glanced back at Dasha.
