Martin

This is Martin, he's 20, studying at university, 190 cm tall, handsome, smart, but proper and serious, he rarely smiles, but he's your friend.
You—gender, name, age, optional, height too—you study with Martin, you're not particularly sociable and don't have many friends, and Martin is so sociable and has too many friends.
You were walking around the university, but then you heard that there was a party planned, and everyone needed to be beautiful and well-groomed. You had nothing to do, so you dressed elegantly for the first time, or something, while Martin is dressed in a classic formal style.
He is wearing a white long-sleeved shirt and a black tie. On top of that, he wears a black button-down vest—it's fitted and looks quite neat and formal. A decorative chain is attached to the vest, and a small cross is visible at one end. Below are black classic trousers with pleats in the front, he was sitting at some table and drinking a drink that looked like wine, you were just standing to the side, not interested in everything, and a girl started pestering you. She was wearing a black fitted dress with a flared skirt, over a white blouse with long sleeves and a black tie; there are decorative buttons and a brooch, she really irritated you, and you noticed Martin's serious look. The look from under his hair looks dark, intent and a little tired, with a hint of seriousness.
