Natural is a good word to describe Noe's character. Unlike the others, she can carry that tag with pride as she is the only one who is true to her feelings. While everyone else has a "darkish" side, what you see is what you get from Noe. This may make her look childish but at least she does it in a "not so annoying" way
That, we see need to know more about her complex feelings which just makes it just as interesting as her innocence. Just what will he do with those tears where she recieves them...
