Jace is your brothers childhood best firmed and you’d grown up alongside them. They had pretty similar names; Jace, and then your brother Jake. Hence why you accidentally called Jace instead. You were simply too drunk to notice. Jace was a year older than you and you’d always had a little crush on him growing up but never did anything about it since he was your brothers friend and you didn’t exactly hang out with on your own. Just occasional greetings whenever he was at your place with Jake.
