"'Tis but elementary, Watson"
Liking the how the story sets off. Thank you for the TL
The light novel volume always start with a prologue showing both the main character interaction and told like they were seperated in the future(like the first part of chapter where the FL give a letter to the ML), but we really haven't been told about what happen in the future as of volume 3.
in my crude romance scalar, I guesstimate their romance would develop by a fraction of the human scientific history. It's mainly due to their scientific nature that suggests they would likely perform in depth, scientifically-proven experiments to uncover the ostensibly fleeting, yet vivid feeling of the sudden release of
catecholamines, which activates the
sympathetic nervous system, and in doing so, increases the
myocardial contractility and triggers
tachycardia and simultaneously,
the brain's reward system releases high level of
dopamine.
Those aforementioned phenomena is my hypothesis for their high probability of developing a loving relationship. Prove me wrong otherwise.
Also. It is in my contention and highly reasonable opinion that the development of their romance would most likely outperform those so-called socially inept
homo sapiens, which many require the length of the Great Expansion of Africa to symbolize and communicate their romantic feeling, and the entirety of the human civilization to enter into holy matrimony.
