That girl ain’t playin with a full deck. 20 to 1 that deck is all jokers, cuz you gotta be real screwy to think saying someone’s name is the equivalent of dating.

That being said, the series being extended for maybe 3 or 4, heck even 5, more chapters could allow for some fun jokes before dropping the bomb to crazy girl. Her reaction to learning her crush was unsuccessfully teaching her how to woo him would be funny.
