Kon Mai Jum Bpen (Unnecessary Person) by Getsunova
Initially I was lured by its melody from a drama based on this song, so I went to check out the mv. Then WOAH. IT IS SO DISTURBING. I LOVE IT. I cried so many times listening to it and it was on loop for several days. Hahaha. I love how disturbing it is because it amplifies the message it is trying to convey!
