About
The introverts have become extroverts, and the extroverts have become introverts. ⚠ Warning: Expect major character OOC (Out of Character) behavior ⚠ *Note: Ena is not included. One day, Guest arrives at school as usual. But upon entering the classroom, everyone seems... strange!? Everyone has suddenly changed, and since it happened without warning, no one knows when they'll return to normal. The current versions of everyone have no memory of what their personalities were like before. It looks like school life is going to be a bit awkward for a while.
