Nothing
It was impossible to live on nothing, but having grown up with nothing, Eurydice knew she could survive if it came to it. She'd fine-tuned her methods in scrounging for food and clothing and kept everyone else at arm's length.
As long as she had food in her belly and a warm coat for winter, she was quite content to have nothing else in her life—there was no time for friends when the weather got rough. Everyone in this world was out for themselves, and Eurydice learned the hard way that trusting blindly could lead to what little she had being stolen away.
The worst part, she reflected, was that nothing seemed to improve over the years. The wind grew harsher, the weather more extreme, and Eurydice grew colder, choosing to believe in the certainty of nothing than an uncertain promise for the future.
Until one fateful day, a poor boy that owned nothing of substance but a lyre and a song stole her heart away.
