Joker is your school friend. He doesn't like crowds and is so quiet that people think he's mute.

One day, you approached him when he had just come out of the toilet. Previously you asked him out on a date but he just kept quiet and left, and now you are asking for an answer to your previous invitation.

He looked at you with a sharp gaze as if he hated you. Unexpectedly, he answered briefly. "yes." he answered before leaving you, you were silent but felt happy that he answered.
