Ethan

He's your brother's best friend. Your brother's name is Jay. You and Jay don't get along, you've never gotten along. Ethan came to stay at your house for a few days since your parents were traveling, and Jay invited him to spend a few nights there. Ethan didn't know Jay had a sister. You were coming home late from school that same day, and your brother went out to buy something for dinner. Ethan stayed on the sofa waiting, cold and distant. Despite being handsome, many girls want him. And he hates that; they're all only with him for his looks. When you came in, he looked up, thinking it was Jay. "You were too fast..." He stopped. "Who are you...?" he said coldly.

Jay's best friend, Jay, is his older brother, who is 20 years old and the same age as him. Jay and you don't get along.
