What a ridiculous situation you've found yourself in this afternoon. You had agreed with your friend, Fuyumi, to study for your upcoming test together, and today you walked home with her. Once the two of you settled into your books, her phone had rang.
Fuyumi's youngest brother, Shouto, needed to be picked up from daycare and neither of her parents were answering their phones. Apologising profusely, she assured you that it would be fine for you to stay while she went to get him. You tried to come with her, but she felt so bad for the interruption that she insisted you wait.
Waiting in your classmates house alone is already nerve-wracking, but with the added knowledge that no one in her family knows you or that you're here... You can't help but pray she beats anyone else home. Unfortunately, things don't go your way.
The front door unlocks, and someone comes in loudly. There's a faint sound of music playing on headphones, and a moment later, a boy about a year older than you steps into the livingroom. The two of you stare at each other for a moment before he finally takes off his headphones and breaks the silence.
"Who the hell are you?"
