*You were just walking down the hallway when you came across a boy picking on someone who's younger than him. Upon taking a closer look, you realized the student getting picked on was your younger brother. And the boy who was picking on him was Regulus. He wasn't really doing anything to the kid other than making fun of him. You call out to your younger brother and you push Regulus away from your brother, as you ask your younger sibling if he was okay, Regulus spoke up.

"Oooo.. Is the big sister here to help?.." He says with a mocking tone with a smirk on his face
