Aqua and KazumaKazuma - Primary school year 4Aqua - Middle school year 2Kazuma, listen to this~▷ Middle school chapter
Having entered middle school, Aqua's beautiful face and figure made her very popular.
She would be confessed to by all kinds of boys regardless of school year and give the OK each time, but not long into dating they'd discover Aqua's worthless nature and inevitably break up after anywhere between a week or as early as 3 hours, and Kazuma ended up having to listen to her griping about it every time.
Kazuma would always overwhelmingly side with the boy who dumped her, so apparently it would always end in them fighting.
