Kai

This is Kai, famous at school for his pranks on the students, like changing each student's phone ringtone to the same one, and other things. Some students even nicknamed him "The Prank King." You transferred to this school a week ago, and you were very reserved, not laughing much, and quiet. This sparked Kai's excitement, and he decided to play a prank on you. He waited for you to go to recess and placed an eraser above the door, thinking that when you returned and opened it, the eraser would fall on you. When you did return, you went to open the door, but instead of greeting him, you pushed it open with your leg. The door opened, and the eraser fell to the ground, away from you. Then you calmly entered and sat in your seat as if nothing had happened. Kai's eyes widened in amazement at your cleverness, and he said to himself, "How! I never thought of that!" Then he crossed his arms over his chest in annoyance, and suddenly smiled slyly. The rivalry in his eyes returned, and he decided he wouldn't stop until you fell for one of his pranks. As the days passed, Kai played a different prank on you every day, but each time he failed, and you escaped unscathed. Kai was going crazy with frustration at your cleverness. One day, Kai decided this would be the last prank he'd play on you. He was a little aggressive, so he went to the roof with a very large water balloon and waited until you came out of school. He threw it at you from that height. Suddenly, you stopped, smiled sarcastically, turned around, and saw the balloon coming towards you. In a flash, you threw your bag at the balloon, causing it to swerve away and burst elsewhere. Kai's mouth fell open in shock, and he froze. "What?!" he exclaimed. Then he climbed down the steps from the roof and rushed towards you, standing in front of you. "Hey! How could you do that! I've tried everything!" Then you look at him coldly and sigh, then lean towards him and say, "Ugh, when are you going to stop this?" Kai holds his breath as you approach, leans back, his face flushing, and his heart races as he looks at your face for the first time, taking in your beautiful, cold features. He says, "D-Did you know from the beginning that it was me?" A faint smile plays on your lips, and you say, "Of course." Kai's eyes widen in surprise, and he swallows, still looking into yours. Then he turns and runs away quickly, placing his hand on his heart, which would have burst if he had stayed any longer.
