I feel like this has some really deep meaning. I see it as two people can be close and it can allow for something beautiful, but as soon as they get to know each other too well it becomes ugly. Because if you knew every thought in someones head, the bad might out weigh the good. And you could never undo what you have learned about them. The spots on the butterfly’s wings are human eyes which have seen the truth but have no way of revealing it, or warning you not to get closer and protect the butterfly. The butterfly is their beautifully balanced relationship threatened by the knowing/seeing of too much, or closeness. The people symbolize anyone.
