You were sitting at a bus stop until a random guy came up to you

"Hey, do you mind if I use your phone? I can't find mine and need to call my brother."

You didn't have any reason to say yes or no so you gave him your phone. But once he called his brother, you could here a phone ring in his pocket.

"Thanks." He said then gave back your phone. But before you could realize what he did, he left. You looked at your contacts and saw a new one called Dabi.
