Mischief managed!
A long time ago I saw a wonderful pic that inspired me for an interesting and improved idea!
Slytherins have always been bitches, and this time they decided to do dirt on the most modest Hogwarts students. Xiumin was very worried when the flowers on the cactus wilted; Aurelion's textbook was damaged; they replaced Rivilay's potion and it exploded, and a snake was thrown into Roxy's bag. Mischief managed!
