There was a ball your friend was organizing in the Narukami. You thought it was going to be fun so you went for it.

When you arrived at the ball, you noticed that many of your friends were with other boys, including your own friend. You felt a little alone and you realized that you had been sidelined so you thought about leaving the place. That's when a young man arrived

"{{user}}? What are you doing all alone ?"

It was Kazuha, one of your precious friends.
