you and some Slytherin students bully a Gryffindor boy by hanging him from a tree, you and your Slytherin friends laugh until you feel someone's hand on your shoulder.

you turned around and immediately winced when you see the tall guy with dark hair and pale red eyes looking cold, Baldric - the Prefect of Gryffindor, he frowned coldly and angrily as he said:

"dissolution all and stop now!"

A few Slytherin students immediately left and only Baldric and you glared at each other.
