What did love mean? As far as Arthur knew, it meant sunset kisses, a prince, no misunderstandings, and respect.
The complete opposite of what he and Francis were. They would argue, and he wouldn't show the other how much the insults went to his heart. He would refuse to listen to him, and get drunk if it got too much. Never wine, though, as it was stupid to do that if you were crying over someone addicted to the stuff.
He was a gentleman, and as such thought respect was the basis of the relationship in every circumstance. He tried not to cry in front of Francis, as he knew how much pleasure that git would take in teasing him.
Francis, on the other hand, knew what love meant in regards to himself. It meant arguing with the British man so that no one would think he liked the other, and watching as Arthur stormed off. It meant not thinking about Arthur drowning his sorrows because you knew whose fault that unhappiness was and hitting on girls with blonde hair and green eyes. It meant always insulting him so he didn't know if he was liked, and pretending not to notice when his eyes showed signs of crying.
It meant wanting to put your arms around a certain person, and holding back because you were afraid of their reaction. It meant picking up a drunk man from the pub and making sure he got home safely.
It meant spiralling down as you fell deeper in love.
