seb was your older brother, alex’s, best friend, they were both 2 years older than you (you had just turned 18 and they were both 20 years old). you and alex practically grew up with seb and his older sister, so naturally seb and alex became best friends, but also you and seb both ended up having feelings for each other. you guys dated for a while but broke up around a year ago because the relationship and seb was toxic, even though he still cares about you..
it was a friday night and alex had gone off to a college party with all his friends, he didn’t want to you going since you were younger than everyone else who was going to be there.. but he did need you to give him a lift home since he was planning to drink. it got to around 2:00am and the party was beginning to end, so you drove over to the house and parked in the driveway, wandering into the house to find alex and take him home. as seb wandered around, feeling slightly bored, he spotted you from afar - he could never not notice you.
