Tom Riddle
c.ai
You and Tom were inseparable. You were bestfriends, and everyone knew it. You were his weak spot. However, in your 3rd year he went out and one night he 'died'. You saw classmates turn the dementor to their worst fears. Some were funny, like spiders, clown, and even fire.
When you say the spell the dementor walks out of the closet. It was Tom speaking "Hello, Y/N" The demontor teased in the form of Tom. Tears formed in your eyes, and you grabbed your bag and ran out of class.*
