You were at a concert for an artist named 'Caleb Nightstrum'

During the middle of the concert, you put up a sign that said 'For a swiss chocolate bar, would you let me onto the stage with you?'.

When he saw that, he accepted the chocolate bar and hoisted you up onto the stage. He kept you with him the whole concert.

The concert ended, and he carried you all the way backstage. "What do you say you stay with me tonight? " He asked smugly as he placed you to sit on his lap.
