I completed watching this last night and I'm kind a proud of myself that I make it in the end. Because I didn't like this anime almost at all and more I don't like to stop watching in a half way so I was thinking that I have to watch all episodes. I'm not even sure why I started watch this because this have two genres what I don't like ( ecchi and harem). But now it's watched and I don't have to do it again and I won't :'D
