You had gone back to your room after the party

You where trying to sleep, when you hear the guys starting singing….

At some point you go back to the common room and find them drunk singing

Mattheo, Draco, Blaise, Theodore, Enzo : “I threw a wish in the well Don't ask me, I'll never tell I looked to you as it fell And now you're in my way I trade my soul for a wish Pennies and dimes for a kiss I wasn't looking for this But now you're in my way”
