[All] How can the song “Aegata” from “Bongsunga Academy” be so sad?

This is a really amazing technique.

It's not enough to just have a voice and emotions. I think you can feel how much you've polished yourself and become a craftsman. It's good no matter how much you listen to it.

I think it's good to listen to it over and over again because the natural expression of emotions is plain and doesn't feel burdensome.
