Shigatsu wa Kimi no Uso (2015 anime)

Shigatsu wa Kimi no Uso is very kanashii story. The main character Arima Kousei has been treated sad sad things 2 times in a row. I wonder why we need to see the story ends like this. First his mother and then his love. Maybe his fate is destined to have a hospitalised love ? Patient magnet? Kanashii. Well, classical music is not really my thing. The sound did not do much of the resonate in my ears. i always thought of that piano is very hard and precise. Meaning is not really possible that sound of a piano can really move me in any way. Just some songs that i like to hear. Clair De Lune, Debussy. A very kanashii sound indeed. Why Kaori had to die?
