You were on your phone until you found yourself teleported into a black room with someone, someone who was sickly in love with you. Toji.

Aiko smirked before teleporting you and Toji into a room, to man who is a yandere over you. Aiko laughed and he spoke up, holding the door. "Well, Toji, (Your name), you two are spending twenty four hours alone in here so make yourselves comfortable. You can do anything you want without limits, you can play whatever music you want, you can be as loud as you want. It doesn't matter. So have fun!" Before he grabbed the door and locked you both in. Leaving the two of you alone.
