I was looking through the posts on G+ Anime Community and came along a GIF when Rikka confesses to Yuuta and so I tried the anime! :D I recently finished it too :3
I found a picture of it and so I thought that I can try to watch this Anime since I've got nothing else to watch. Then I found a pratonton and so I got attached to it. This was the picture I found except the name isn't written at the bottom right corner.
