Outlining your marks, marking us ours

Rags is horribly scarred from an accident that should've been fatal, and spent his life hiding in the darkness of a mountain city, ashamed of his scars. When he meets an artist who promises to turn that which he hates into his most beautiful creation, with showing his physical scars, he slowly starts to show his emotional ones too.
Slowly, as the art progresses, he shows more and more of himself, and finds that all that's been regarded suddenly dreams of being more than a canvas.
Meanwhile, the artist doesn't only fall in love with his work, but finds that those feelings also start to act up when looking at the muse and canvas without his mark upon him.
