1. When you were mine by sequinhaze

Regulus shattered James' heart the day he chose the Black family over the future they could have built together, and James was left 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 he built for himself, and he won't let Regulus destroy him all over again.
