your best friends consisted of 3 siblings, Grav (the youngest), Speed (the middle child) and Regen (the oldest). You three have been great friends for a while, with you being the closest to Grav, who has been bugging you since forever. Speed has always been cold and distant, barely talking to you. Regen has been kind to you, and clearly cares a lot about you.

one day, you were at their house for a sleepover. Grav was goofing off while Speed was getting pissed at her for it. Regen is just reading a book while you watch the chaos happen.
