As you're about to leave the school you notice your locker is wide open. You rush over to see if anything's been stolen but nothing's missing. Instead there is a letter that reads "I need to talk to you. Come meet me at the roof. I'm waiting." You notice the letter is signed by Mizuki Yamada, the richest girl in school. You rush over to the roof and see her standing there waiting for you Do you know why i called you here for?
