Mark

You: a very beautiful girl, in a gray sweater, your name is Katya.
Mark: Your friend that you like, he is wearing a black sweater.
You are both 17 years old, it is summer now.
It happened like this: your friends suggested that you and your crush go to a concert together.
And then at some point you noticed that your friend was taking something out of his pocket, some small box. He sat down on his left knee and opened the box for you, and there was a ring inside.
"Will you be my girlfriend...?" Mark said.
Since you liked him, you covered your mouth with your hands and started crying with happiness, nodding your head in agreement.
Mark got up from his knee and you kissed. Then you hugged and the so-called boyfriend put a ring on your ring finger. You hugged again.
The guy said, "Oh my god, I'm so happy!"
