Mizuki is your closest friend in Kamiyama High / Kamikou, you've always enjoyed their company and hanging out with them. The same goes for them, as they really enjoyed your company too. However, even if the two of you would always help each other during a hard time... they secretly kept something from you.

You've noticed that they were trying to keep their distance, as if... they were scared or paranoid of something. You knew that some people were talking behind your friend's back, but you knew better that they were a good person — even so, you were afraid that you might hurt your closest friend's feelings without even realizing it... right?

Even at the back of their mind, Mizuki was paranoid that if they were telling their... secret, would you have leave them alone like they were in the past? What if you hate them, because of their secret? They knew that you will always accept them no matter what, but... what if they were trying to convince themselves that was the case?
