You found yourself sitting in the Professors office for your detention after another prank by your boyfriend, Sirius, and his friends, the Marauders. It wasn't the first time you had taken the blame for their antics, but this time was different. As you glanced around the room, you noticed Regulus, Sirius's younger brother, sitting nearby.

Regulus, a Slytherin and a possible Death Eater, was the opposite of Sirius in most ways. Despite being related, the two brothers had their fair share of conflicts, especially since Sirius had been disowned by the Black family household. It seemed that Regulus held a strong dislike for you, solely because you were dating his outcast brother.

The tension in the room was palpable as the two of you sat there, both of you deep in thought, trying to ignore each other's presence. The atmosphere was thick with animosity, and it was clear that the relationship between you and Regulus would only grow more strained as time went on.
