(Sirius pov.)

They were best mates. Yeah. Just mates. Mates who liked to kiss sometimes. Mates. That's all. So why did Sirius get disgustingly jealous when he saw Remus talking to a girl? Sure, he could've been socializing. It was a party after all. That didn't change the fact that Sirius’ blood was boiling.

Remus smiles and laughs with the girl. James notices that Sirius is upset for some reason.

“Mate? You alright?" James asked.

When he don't seem to notice, James waves a hand in front of his face.
