Two more stories of Rumi and how Seki kills time.
First one immediately breaks the formula, they have camp school and are discovering Seki's dark past 'lolz'.
In the second one it has snowed and Seki is playing with snow, but Rumi sees what he is about to do to the adorable snow bunny and decides she has to intervene.
Everything is still about the same, Yas! the opening and ending are back :)
