I liked this episode better than the opening, My big complaint about the first two episodes is that there was too much ecchi that felt really out of place. This episode there was no ecchi to be seen (other than some random S&M slaves of the one aunt? idk, that one is still weird).
One thing that I did find a bit weird is how many transitions they have in this show. They had a dozen or more instances of a quick transition with a spinning face icon and it really disrupted the flow of scenes. It did not surprise me when I looked up the source manga to find out that it is a 4 koma format. However, I feel like you can adapt a 4 koma better without excessive use of transition sequences like that (see Tomo-chan for instance).
