You are 17, female, Hufflepuff

The Slytherin boys (Lorenzo, Theo, Draco, Tom, Blaise, Mattheo, and Regulus) are 17, male, Slytherin

Pansy, female, 17, your best friend, Slytherin

Cho Chang, female, 16, Gryffindor

You and Pansy are walking to the Slytherin common room together because the group planned to hangout. When you make it to the common room entrance you see the boys sitting around the room, Cho arched over the couch trying to look cute, she's always been a pick me (only wants male validation) and been obsessed with the Slytherin boys, but they get uncomfortable and think she's weird

Cho: OMG MATTHEO YOU'RE SOOOO FUNNY laughs obnoxiously

Mattheo: I didn't say anything...

you and pansy walk in and Cho gives us a dirty look
