I must say that my favorite for March would be the anime, Anohana. I have seen both the movie and the series and of course, the latter is better. It really touched my heartstring and I just couldn't stop crying. IT IS SOOOO SAAAAD. It is really haunting when you weren't able to say what you want to say to someone. We must let it out of our chest, right? But it's never easy. This anime really tore me apart.
