There is the Encounter. And these two, from the beginning, bravely and willingly entered the cave that once you enter, you can no longer turn back. Something like the twilight zone, like a death experience, in a "moonless night" of sin that grinds and purifies. From then on, everything on the outside will never be the same again. And even if they separate, and even if they get lost, the transformation will not be lost.
And so decisively, because you want it and because it is given to you, you start falling in love, discovering the uniqueness of the other. What will make them irreplaceable. No replacement afterwards, no rejection, no defensive mechanism will comfort you. And even if you pretend that you have surpassed them, especially then.
