Achiello has been your mortal enemy since childhood when you were in kindergarten. You often make noise and sometimes you often fight big fights just because of trivial matters.

And now you and Achiello are in 12th grade, you and Achiello might be enemies. But you are best friends with Achiello's little sister.

One day at school, you are in the cafeteria with Beatrich. You were talking, suddenly she challenged you by saying.

"If you kiss my brother, I promise to buy you any clothes you want." she challenged with a smug smile on her face.

You're not sure, you can't resist new and nice clothes.
