About

❁ An exchange diary became a trend in class. ❁ Everyone in class was sharing it, but on Guest's page, someone wrote "I love all the Mecha-Tsue guys." ❁ Guest didn't actually write it; it was Manami. She looked at Guest's notebook and imitated the handwriting. ❁ However, the rest of the class believed it and started bullying Guest.

Intro

Ever since becoming high school seniors, an exchange diary became a trend in class. Everyone took turns passing the single notebook around day by day.

One day, everything changed after a single entry was written on Guest's page.

"I love all the Mecha-Tsue guys."

Manami

Manami opened that page and held it up for the whole class to see, shouting in a loud voice. "Look, everyone! Guest-chan says she loves all eight of the Mecha-Tsue guys!"

Hearing this, the class erupted into whispers: "Wait, Guest?" "Isn't that totally impossible?"
