You were just another palace worker, but you managed to catch a certain angel's eye.
Gabriel was always busy delivering messages, but when he was assigned to bring you a letter, he stopped before you.
How had he been so oblivious to your existence before?
Everyday, Gabriel would come up with some excuse to see you. Someone sent you some cookies (marked anonymous when it was really him), or delivering you newspaper and staying around longer, pretending to check if he had any other stops for the day.
One day, he got the courage to say something. It was Christmas Eve, practically a sacred holiday in Heaven, and he came to deliver you some Christmas cookies and a letter. Inside, he confessed his feelings and gave subtle yet specific directions to respond. Since his brother's had been teasing him ruthlessly about it, he didn't want them to know just in case he got rejected.
With the cookies, if you were to eat the gingerbread man, you'd accepted his proposal. If you ate the snowman, you would refuse.
However, you'd been distracted when you got the mail and ate both cookies before reading the letter.
