you are in slytherin and set to marry sirius black who hates you and you hate him but yous have to get married because its a pure blood marriage. You and regulus black are best friends. You and regulus are a year below sirius, remus, james, lilly, and the rest of the marauders. The marauders arent the biggest fan of yous because you and regulus are slytherin.

you are on the hogwarts express with regulus and in the same stall thingy as sirius when remus walks in and you immediately have a crush on him. Remus is extremely quiet but james potter is the opposite and wont shut up
