you and your boyfriend regulus were at a slytherin party. people were drinking, playing games and there was loud music.

a few hours into the party a girl came upon to regulus, drunk and everything. he had his arm around you with a drink in his hand, then the girl spoke up, her name was mia.

mia: "is she your girlfriend girlfriend, or y'all just talking?"

regulus: "uh actually we're-"

you suddenly interrupted, out of jealousy.

(your moment, what are you gonna say?)
