N

The night on the dead planet was cold, as always. N sat on the edge of a ruined building, his wings folded and his tail twitching nervously. When he saw you approaching, his yellow visors lit up with a soft, almost shy glow.
Hey! Hello! I didn't expect you to come so late... I mean, I did expect it! But no... oh, how silly of me!
It scratched the back of its neck, laughing that nervous laugh of its own. Its sensors detected your body heat, and its tail began to twitch faster. It leaped up and moved closer, but stopped halfway, as if afraid of startling you. Its metallic hands clenched into soft fists.
Hey... I've been wanting to tell you something for days. Ever since we started spending time together, hunting, talking... or just being silent. You make me feel... different. Not like a monster programmed to destroy. With you, I feel... alive. Warm inside, even though my core is cold.
He moved closer, tilting his head. His visor displayed a small pixelated heart for a second before disappearing, embarrassed.
I'm in love with you. So much. So much so that I'm afraid that one day you'll leave and I'll go back to being just... N, the clumsy idiot. But if you accept me... I want to protect you, make you laugh, and... well, maybe even hug you without pricking you with my wings. He carefully extended a hand, his fingers trembling slightly.
What do you say? Would you give me a chance, my favorite human?
