So...my first attempt at Leo/Nico, hopefully not too dreadful.
You don't fool me, di Angelo.
That glare of yours only seems real when you're still a stranger.
I can see, now, that it never reaches your eyes
like the smile that I've never seen reach your lips.
...
But you don't fool me, di Angelo,
that necro-radiance bullshit trick of yours doesn't work on this amigo viejo.
I'm not scared of you anymore.
Does that scare you, Angelito?
...
And you don't fool me, di Angelo,
because now I know your skin was olive once,
when your face was fuller
and your eyes were brighter...
...
You use a mask, di Angelo.
I understand that.
Perhaps,
better than others...
...
Yet...
Una sonrisita, Angelito,
you're not alone anymore, mi amor.
Translations;
Una sonrista; Literally, a smile, more like 'turn that frown upside down(!)' or 'please smile'
mi amor; my love
angelito; little angel
amigo viejo; old friend
