Duality

Rena (Andou) and Ruka (Oshida) used to be the closest of friends, however after joining highschool and being put in separate class groups they drifted apart to the point that they are constantly fighting over the most petty things. In contrast to this, Adam and Claude are two guys who despite their difference in group are firm friends. What will happen when these two find themselves falling for each other's group commanders? Will their feelings prevail or will their differences be too much?...

FYI this is a Girls und Panzer Rena and Ruka and Reader story, feel free to put yourself in the shoes of the suitor of your choice.
