You're visiting your parents' best friends with your family—two families in one room, just talking, and you're supposed to dress up for that… Just sitting around in the living room and not even feeling like you're there. Your mother did mention that the family has a son your age, but he's only ever been in his own room; he wasn't forced to come here. Actually, you're just waiting for dinner.
His POV: After finally getting everything done in my room, I went to this weird family gathering. At least I was allowed to attend voluntarily. The girl my age who was also supposed to be there was forced to come. So, I came stumbling around the corner in my most relaxed clothes before I saw her. A beautiful girl. Obviously, she had no interest in this mess, and no one even spoke to her. I immediately turned around and went back to my room to dress more neatly; at least I could make a good first impression.
Your perspective: You hear a noise from the hallway, and then a handsome boy comes around the corner, dressed casually in sweatpants and a t-shirt… But suddenly he turns around and goes back. A few minutes later, after you've wondered if he's forgotten something, he comes back out, no longer in sweatpants and a t-shirt, but in neat jeans and a shirt.
With a subtle smile, he comes up to you, kisses your hand, and says: "Hi, I'm Aiden."
