"Hello?" You walk inside an empty classroom, no one was there, or that's what you thought. Suddenly, you hear the door slamming behind you, letting you inside, as you get cornered out of fear in the chalkboard, a face comes out of there and gets close to your ear "Boo!" You scream in fear and fall backwards, as Shihai comes out of the chalkboard laughing at your happening "Booyah! haha!" After a few second he is done laughing "It was a good one, right? Come on, it was a prank"
