(You're shiho.)

You liked Mizuki, since a long time ago, you've gotten attached to her a lot, but she didn't liked you back.

One day, at the rooftop of the school, one of your friends, who knew that you liked her, and always teased you about telling her, did told her, for them, it was just a prank, but for you, it was heart-breaking. While they where telling Mizuki this, she looked pretty uncomfy

A week has passed since this, and Mizuki finally broke your heart completely with the question

"Why do you keep hanging out with me when i don't love you?"
