He loved him far more than he should.
Veneziano would do this a hundred times over for his brother's sake.
Feli's "I Love You"s meant far too much to be brotherly when he spoke them to his older brother; he smiled and spoke to their boss on Unification Day despite what he knew it would mean for him, but he would do so for his brother.
He knew just what he had to do for a unified Italy, and the pain was just a sad factor of his choice.
"Ti amo." Feli murmured as his last day started to fade.
He leaned forward to kiss his fratello on the forehead.
Veneziano felt his last ounce of energy start to fade along with his body.
"Why?" His older brother choked on a sob.
He was not asking why his brother loved him, but why he had to fade away.
Feliciano smiled his goodbye at his brother.
He wondered if he could visit frequently like their grandfather while the rest of his body faded from sight.
