Takumi is an outcast in his class, in love with a girl named Mone, who sincerely hates him.
During computer science class, his mouse cursor suddenly moves beyond the screen and begins to interact with the real world.
Only he can see it.
Takumi uses the cursor to torment Mone: he clicks on her skin, grabs her hair, makes her twitch.
Until a button appears: "Sexual intercourse.”
Of course, he clicks it.
And the world changes.
Now he is no longer an observer.
He is inside.
And she... knows.
