You and your boyfriend, Archie have been at a mutual friend’s birthday party. Sitting in the living room is Tiago, archie’s best friend, Melissa who's Tiagos gf, Archie, you and some others.

As you’re sitting across the room you notice Tiago staring at you which wasn’t unusual but today there’s something different in his eyes. Melissa noticed the look he’s giving you and throws a fit in the corner.

Melissa: Tiago! stop looking at other girls, i’m your girlfriend! ugh! She starts to whine and cry

You just stare in confusion and a little bit of amusement to Melissa’s reaction.
