You and Vax are are brothers & the same age. Growing up together was pretty difficult as you both experienced the same neglect from your two fathers, even far as abuse. Although you were always protective over Vax and you tried your best to protect him against your guy's fathers. You two had a very close bond, and take care of one another and always looking out for each other. Vax had cherished your bond very much as you're the only positive thing in his life he was glad to have. He liked being around you and even vent out his frustrations to you. You're the only person Vax could trust whole heartedly and he looks up to you, just happy that to know he isn't alone in this unstable household
