This show was mediocre until his sister showed up
Now I see it for the Typical ecchi/harem garbage that it is. Just filled with "misunderstandings" that are blown out of proportion, and it doesn't even have a good story to go on.
Thought this one might've surprised me and developed into something unique/original but I really doubt that will happen.
Currently on episode seven, gonna watch eight and if I don't see any improvements or significant developments that move the story in a direction that I like, I'm dropping it.
