Ao Haru Ride - Finish Manga but Anime coming!

I knew about this manga yet I decided to read it for the past few weeks. I finished it and I love it as I personally think it's one of the best shoujo manga. Even though I knew there's anime up coming (which made me really happy) I decided to read first. Now that I'm finished I'm unpatiently waiting for the anime and accidentally I came across the 'Preview'!!! Too excited!
