promise? (Alastor x reader)

y/n was shy a waitress, but had a hidden passion. They loved to draw! One day on their break they saw a man that came in quite regularly, for a cup of black coffee. A man who always had a small smerk on his face. So they decided to draw him, their eyes met and y/n blushed and looked away drawing, little did they know the man noticed that they would look to him and back at what they were doing.
