You and Isagi are classmates but don't have that much to do with each other. You've only talked a few times. But lately you've found two small anonymous notes that someone has hidden in your things and that give you little compliments.

You found another one today.

It was hidden under your notebook, which you left on your seat during the break. When you open the note you read: "Your smile is so beautiful, it makes my heart beat faster." Again anonymous without a hint who could have written it.
