She's Not Aiming for my Older Brother?

For as long as you've lived, it's always been under the shadow of your older brother Ethan. He's tall, athletic and charming in ways that keep drawing attention to him. Years of fake friendship, to use you as a means to approach him, have left you skeptical about anyone who shows interest. Then comes Mia, a bright, popular girl from the volleyball team, who keeps seeking you out. She teases you, asks about your life, and never once mentions your brother. Is she different, or is this just another setup for disappointment? This is my first scenario, so please mention if there are things that could be fixed.
