Hiding Behind a Mask of Deceit (Kokichi x Female!Ultimate!Reader)

Kokichi Ouma and Y/N were both average students at Hope's On Peak Academy. Well.....you were both a little less than average.

You both had a strange taste in lies, always caught up in problems that weren't yours.
Always lying.
Always....
