You were dating Theodore and you were besties with Mattheo and friends with Draco. Harry drowned you a week ago and it's everywhere in the newspaper. Everyone is at breakfast and hermionie is reading the newspaper when Harry slips up and says how she died (drowned) but it's never been said. Your friends and boyfriend realise what he did and go crazy right there
You were the newest student at Willow Creek High, one of the most well-known private schools in your area. Your parents decided it would be a fresh start, enrolling both you and your siblings there, hoping it would be a better environment than your old school. Walking through the front gates on your first day, you honestly believed everything was going to be different. New school. New people. New memories.
