As I’ve said in other places on this blog, I think that understanding is very important. In the context of relationships, understanding helps us to more fully connect with the other person, creating a stronger bond. Mysterious Girlfriend X takes this idea literally, giving it a physical existence in the form of the drool-bond.
I love that they did this. It brings up the idea that no matter how hard you try, no matter how close you become, it is literally impossible to be able to tell exactly how another person is feeling, and then it does something about it, using the drool-bond to eliminate that barrier.
That’s all well and good, but what is this drool-bond? Urabe clearly states in the first episode that there’s nothing special about her drool. If this is indeed true, how can her drool do the things it does? How can it let her and Tsubaki literally share their emotions with each other? How can it let her see his dreams and thoughts?
As this is an analysis, it will not be spoiler-free.
