Yuu is a bit special, but I think his issue is largely trying to do things the way a genius would, when he is far from one. This chapters shows it pretty well, the girls are pretty shit at teaching him anything because to them it's just a matter of "feeling it". If he was following the example...
Even the most dragged out of romcoms manga will have something happen, even if it's just filler. This is just the premise being reinstated endlessly, hence why I assumed the author just wants to draw these two doing poses and nothing else.
