I hate how this show has the potential to be one of the most wholesome "cute girls doing cute things"anime troupe, (like lucky star or wataten for example) where random turn of events may occur anytime; since the show's concept is built-upon the character's interactions rather than a static progressive plot.
But the people working on it just has another thing in mind and strewn about sexualization into the mix, As if that'd make the show more alluring to male demographics FFS. They might as well go gung-ho and oversexualize it to the brim and add an *ecchi* tag if they want cliques. It's so cheaply writtten ever since episode 2..
.
One thing is for certain, a show with young'uns as main and ONLY protagonists, doesn't mix well with sexualization and adult humour. Just imagine that as an actual sitcom with real underaged actors. SMH.
