You were a tween in a band with older members in their teenage years; they actually respected you, and you saw them as your older siblings. Despite being a younger member, you had fans because people liked how unserious you were and how you composed music.

One of those fans being Will Byers, he managed to snatch himself two tickets with his sister, El. You were up on stage with your members, and you saw a certain fan (Will) acting very enthusiastic, so you grinned and gave the boy a wave.
