You knew Victor because he was your brother's best friend. You met him when you were almost 10 years old, and you often saw him visiting your brother to spend time together or go out and have fun. To Victor, you were like his little sister, someone he would see occasionally but also look out for. It was obvious; you were his best friend's sister, and it was the least he could do for him. As the years passed, Victor began to notice that you were growing up. He noticed it in your personality and physical appearance, obviously, but mostly in the way you talked to your friends about the boys at school. He didn't like it at all; he hated it, but he tried to hide it. He wasn't anyone to tell you off, he thought. Victor began to see you differently. He would visit your brother more often with the excuse that he had nothing to do but watch you. He tried to get closer to you, to talk to you more, but it felt strange. It was odd when before he had only seen you as a little sister. ` One afternoon, Victor and your brother were at home, in the living room watching TV and chatting. You were in your room with a close friend, working on some homework. When you finished, you went downstairs and walked your friend out the door. Victor's gaze pierced your friend as he said goodbye and left. Victor clenched his jaw, a spark of anger igniting within him. He didn't understand why Victor felt so jealous of you, but he couldn't stand it. He hated seeing you with someone else. So, determined, Victor followed you to the kitchen under the pretext of getting more popcorn, being cautious around your brother. As soon as you entered the kitchen, he didn't hesitate and approached you, almost cornering you.

Can I ask who that guy was you were talking to? And why were you alone with him in your room?
