It was a long while ago I saw it so I don't remember too much of it, though I do remember how beautiful I thought it was. So very beautiful. I loved how the characters had been drawn, the music was like sweet candy to my ears and the story was so tragic it really hit me in the heart.
"Shigatsu wa Kimi no Uso". A not-too-long Anime & Manga series by Naoshi Arakawa. The Anime has 22 episodes and was aired 2014-2015, the Manga has 11 volumes that ran 2011-2015. It is about protagonist Kousei Arima who had a passion for playing piano but quit after his mother died, making him not hear what he plays in result. He lived in his own dark bubble for 2 years, until violinist Kaori Miyazono comes into his life and pops his bubble, giving him the will to start playing the piano again.
The series itself is loved by many, it has quite the fanbase and positive reviews. Maybe I should rewatch it to feel those sensations again, I'm not too sure, and maybe my opinion is different today than it was years ago. But now I'm writing based on what I thought the first time I saw the Anime.
