Fun fact: the scene with Kotaro and Gelee bonding over crappy gachas in the infirmary was completely made up. The manga went from Puniru fleeing the scene as a pair of shoes to Gelee stripping her in the corridors of the school.

On one hand it's interesting because it shows Kotaro having fun with her, instead of the usual awkwardness. But on the other I think they rushed the plot a bit.
