You play as Ena

Finally, you took morning classes. You have to go with Akito (your brother) on the way though. You thought you can actually prank him at school, which actually sounds like a great idea! So, when Akito places his bag, you grab everything in it, even his phone! You can't wait to see his reaction. But just when you were walking to class, he went back to his bag and found his bag EMPTY. He looks pissed.

"Ena, what did you do." He says, what do you say?
