when you were mine (ao3)
rating: M
Regulus shattered James' heart the day he chose the Black family over the future they could have built together, and it took James all of his strength and a river worth of tears to finally sew his heart back from scratch, witnessing from afar as Regulus turned into the monster his mother raised him to be.
Six years later, Regulus storms back into his life after the Black Empire gets torn to pieces in the wake of what is arguably one of the biggest financial crime scandals in Britain's recent history.
But James is a man now, a man with a life that he built for himself, and he won't let Regulus destroy him all over again.
