Rumbling Hearts is on my list to see. You also try (if you haven't)
Ah! My Goddess,Honey and Clover,Air,Place Promised in our Early Days.
Well I gotta say if you're prone to emotional moments, then keep a tissue box close by when you finally do watch Rumbling Hearts
. Its only fair to warn you that it gets pretty depressing at some points. Best to have a pick me up
anime to watch after you finish. There was stuff that bothered me A LOT
, so I ended up watching the whole thing in one day because I just couldn't leave it in the more depressing parts of it.
