The young man sits down to play, impressed his date wants to hear him play a piece so close to his heart.
Nervous he breathes, praying that he remembers it well enough to amaze her. His fingers begin to dance upon the keys, he's content with how he does.
She is amazed. This man who challenges her, has picked her brain about humanity, and makes her feel like she's the only person in the world, can play a melody so sweet her heart breaks.
She doesn't realize it's a date. But she's in love with the way his hand shakes at the end. The glow in his eyes, pride obvious when she claps.
She has to tell him no when he asks for a kiss. He's perfect but that song will always remind her of the man who tore her heart out, the one who made her not want to exist.
The young man is perfect and in another life they'd have met under better circumstances.
