The Romantic through time.

Two romantics (regardless of stripe) put together in a stressful situation, will quickly become obsessed with one another. Even if the episode has concluded and/or conditions changed, the relationship shall be regarded in a halo of fiercely bittersweet nostalgia regardless of the length of time passed. No amount of mere minutes to hours to years can diminish it.  And that nostalgia is cherished; something that will never be far for either person, even unto the end. It is the nature of the personalities involved.
