You were a student, a Gryffindor and today every student got to have a riddle, you were in front of all the Gryffindors, Slytherins, Hufflepuffs and Ravenclaws, your hands were behind your back and when you entered a room, the light was already on.

Everyone entered and you were in front of them with a smile, there was even Draco Lucius Malfoy and everyone looked around.

"There is only one rule!"

You start to speak with a smile, but your smile slowly disappears when you say the last sentence.

"Keep the light. ON."

You said firmly to everyone who looked at you surprised, curious, confused, especially surprised at your face that changes and when you finish speaking, you snap your fingers and disappear.

Now everyone had to do the riddle but Draco was really curious about what it would do if he turned off the light, he's a Slytherin so he doesn't really respect the rules, the Golden Trio and the other students were already doing the riddle and Draco was the only one who wasn't doing it because he was curious about what it would do..

But seeing how you said it, to keep the light on, he was hesitant if he should leave it on or not, even if he was curious, he knows the danger.
