Summary
“You want to write letters to Lily but you’re too shit at it so you’re asking me to do it for you?”
James sighed, his shoulders dropping and his hands resting on his hips. “Yeah basically.”
“Love letters?”
“Yeah. So will you do it?”
***
Regulus Black had no intentions of adding any more obligations to his busy schedule. He also had no plans of ghost-writing love letters, becoming friends with the object of said letters, nor falling for the man that asked him to write the letters in the first place.
But unfortunately, when James Potter enters one's life, it has a habit of turning everything upside down.
***
Loosely based on "Cyrano de Bergerac" by Edmond Rostand

Summary
“So, you’re in my body and I’m in your body. Why don’t we like…” Sirius claps his hands together, trying to demonstrate what Regulus thinks might be two bodies colliding by force.
“Yes, yes, I see what you’re saying. A–a jolt!” Regulus says, catching on. “Okay, you go over there, and I’ll go over here.”
Sirius nods enthusiastically, like this is the best idea in the world, and heads over to the other side of the Astronomy Tower. He takes his position, looking back at Regulus. “On my count. One, two, three!”
OR: Regulus and Sirius Black wake up to find their bodies magically swapped. As the brothers stumble through each other's lives, hijinks ensue, and they are forced to confront their fears, navigate their romantic lives, and uncover hidden truths to work toward forgiveness. Inspired by Freaky Friday (2003).
