Music of Life

(Explanation)

This is how I see this story arc. You can interpret it differently, but this is how I see it as I write it.

So, without spoilers to what's coming in the story arc. . .

This story arc is about a boy and an insane girl he loves obviously. Basically, what's happened so far is that the boy has a lot of enemies. They kidnapped the girl and abused her. Her mind was broken by the traumatic experience of being beaten and sold to different enemies of her lover. The boy eventually rescues her, but she's already insane, which is why all of her 'rational' singing is in a black void. Aka, her mind.

On a side note, they only sing solos, because they don't really live in the same world. The boy lives in the real world, the girl is trapped in her own mind.

So, that's kind of a backround information/what's happened so far in this story arc.
