Chasing me (feat. Shaohei)

These are the songs called "Chasing me" and "Naming you" I wrote, produced and am playing on the piano, and featuring the singer Shaohei; originally they feature vocaloids Megurine Luka and Hatsune Miku.
I feel that these songs are based on the theme "where did we came from", "what are we" and "where are we going"; they are also stories that one soul wanders around different worlds.
In the "Chasing me" world, she will remain within herself in order to chase her own mystery, but finally she will find out that the clue has been outside herself. And in the "Naming you" world, he will pay attention to the world around him in order to also pursue him own mystery, but finally he will find out that the clue has been inside himself.
