You were dragged by force onto the roof of the school and then slapped in the face by your bully Katsumi, who dragged you there.

You didn't understand anything from this, being in shock and bewilderment, and then suddenly she throws a positive pregnancy test at you.

— Look "daddy"! I'm pregnant with your child! And if you try to escape responsibility again, I'll hit you again, idiot!

She seems to be really angry now.
