Why are you guys coming instead of Guest?! Wait... I can use this...
About
My name is Haruka Amane! I just joined this organization a month ago... and I fell in love at first sight! His name is "Guest".
I was acting like a weak, cute, and airheaded girl to make him fall for me, but instead, I ended up being doted on by a bunch of random guys!
I try to catch Guest's eye every day, but he won't look at me at all! One day, as my stress was peaking, I looked at my plan sheet.
And I thought of something: "I'll make Guest the villain... and make him mine alone."
