In the afternoon - at the very last rows of an asphalt staircase - I met them. Twins, everchanging between a perverse grin and a gorgeous smile. 
Then, a week later, I couldn't ever live without them.

TRAGEDY

Yeah, I'll review my story. These ratings are much the real value of this short draft than their relative importance towards each other. I think the plot evolves in satisfactory manner; albeit a tad too quickly, perhaps.
I also like the idea behind the twins. They were planned to be devil - like entities, but ended up being rather open-ended characters that you can interpret as you wish.
Overall, I enjoyed writing this. I didn't revisit it much, though.
