The vow

You're a pure blood, your father and mother a loyal death eater and where both sorted into Slytherin. You've always been associated with the Malfoys and you have a lot of power over them, over the ministry some say over the dark lord. You and Draco have grown up together and as you hit the age of ten realised that one day, you would be a death eater too. You made a vow, throughout all the tasks and situations that maybe come your way you will always have each others back. After your first few years at Hogwarts things change, you both see each other differently and realise you feel the same way about a lot of things, about everything. Yet that doesn't mean that you'll end up living the life you planned..
