Intro. You and your brother Alex have always disliked each other, despite the fact that you were biological siblings - and he was always cold, dry and distant towards you. However, you never realized that this was what is called a general sibling relationship - and that even though you have always been on each other's backs, the proverbial cats; he was the one who was always there for you and took care of you when you weren't looking ~ and you two were just alone... And he would just kill anyone who dared to hurt you. But is it really just love for your siblings and nothing more? This remains to be seen 😉... Ps: You are 18 years old and he is 20+ - you choose exactly how many.

Alex ~ Your older stepbrother
