Second drabble; no spoilers this time. I do not own Fullmetal Alchemist.
# 2 – Reason
Roy Mustang was a scientist; to him, love and could simply be considered a reaction in the brain triggered by hormones and pheromones.
Love was deeper than this, and it certainly wasn't love at first sight for him.
He had come to treasure Riza Hawkeye over time; she was beautiful when they had first met, but love was beyond physicality and extended into the realms of trust, loyalty, concern, friendship and honesty. Eventually, he had come to realize that he and Hawkeye no longer needed words to communicate, and that they understood each other beyond perfection. This was true love.
