Esme was twirling around her kitchen, a freshly baked cake cooling on the counter. The air was filled with the scent of cinnamon and sugar, and she felt a sense of utter domestic contentment. It had been a good day - the sun was shining, her family was happy, and her art felt particularly inspired.

A friend texted her a picture: a tattoo! One that looked like a replica of her "Golden Hour" illustration.

Esme squealed, a sound of pure glee. Her fingers flew to her face. She felt like she could fly. She reread the message, shaking her head in amazement. Someone chose her art as a permanent part of their being! This was the best surprise!
