Press the green flag! (you should probably see the Daughter of Evil project to understand this) This song is about the princess's brother, who cared about her dearly, swapped clothes with her when she was supposed to be executed. Therefore, the brother got killed instead of his sister. This just always pulls at my heartstrings because he sacrificed his life just so his sister could live on... (Last line of lyrics means, "Somehow in our next life, if we ever meet again, let us play together once more, and be the best of friends")
