Great melody. I think that if you put some text on it, you would get a good musical composition. The main thing is that the text is legible so that the listeners do not have to get lost in the meaning of the song and in its translation. I imagine that Korean lyrics would be suitable for this melody. I read on the site https://culturized.com/ that this is a difficult language to understand, but I am sure that it is the Korean verse that will go well with this melody.
