My meddling trip to Hogwarts

Asta is your normal girl - though a little bit introverted - but she has an obsession. With Harry Potter, fanfiction and yaoi. So, what will happen if this yaoi fangirl is magically teleported into the Potter Universe? Do you see where I'm going with this? - Yaoi means maleXmale - don't like, don't read. Pairing: Sirius/Severus, Side!Lily/James [OC is not paired with anyone!]
