2SiriuslySapphicNarcissaFreaky Friday au (bodyswap), Sirius and Remus. Both have to deal with the benefits and negatives of being the other person. Remus learns what it's like to be unfairly gifted with good looks, popularity, talent, etc. Sirius gets a bit humbled without those things but learns what it's like to have parents who genuinely take care of him. Remus has to deal with Sirius' abusive fam, brother drama, pureblood politics (him sitting at dinner or at a posh party in Sirius' place trying to do everything right). Sirius has to deal with being a werewolf. They become closer friends by the end of it. Narcissa knowing he was innocent but (for whatever reason) not choosing to advocate for him to stay out of prison, a past relationship (potential infidelity while she was married to Lucius), a lot of anger and guilt that they haven't been able to express up until now, violence, loud arguments, those deep connections with someone you hate but can't help but love, rough sex underage, scat, these feelings being resolved too quickly
