The story will indeed end soon ... alas ... but hey, at least it is getting an unforced/un-axed closure. That's already something good in the manga field ^^
So we didn't notice how big Kiyo's gotten because she's been growing in millimeters then a singular centimeter. The half a centimeter then millimeters again then two centimeters.
Did....did Granny just confirm that she's been shipping Kiyo and Suu-chan?
