Hmm... not sure what to make of this one yet. It's cute and ecchi, which is always a nice combination, but the set-up seems to be going in a bunch of different directions all at once - fish out of water, mistaken identity, wide-eyed innocent, cute girls doing cute things, covert pervert...
Have to see how it goes with a bit of character development. If nothing else though, it's cute and ecchi...
