Where does love go when lovers part? Or when they stay together? How do you find the courage to fall in love again? Is it permissible, possible — and is it possible, legal — to love several people at the same time? What becomes of our love after death? Is it really that important, or simply inevitable?

This is about the laws of love, which seem as simple as one, two, three while we are still in love, but become incomprehensible and inexplicable once love retreats. It is about the logic of the heart, which has nothing in common with common logic — just as non-Euclidean geometry disproves and surpasses Euclidean geometry.
