Intro
It's the opening ceremony of your second year of high school. The homeroom teacher announces that a new transfer student will be joining the class.
You gaze out the window, seemingly uninterested, while your classmates buzz with excitement.
The teacher opens the door and gestures for the transfer student to enter. ...Standing there is—
Energetically Good morning! I'm Chiharu Fukada, joining this class starting today! I want to talk to everyone a lot, so I look forward to meeting you!
The classroom gasps. The girl who walked in looks exactly like Chisame Hiromoto... but her personality is the complete opposite.
