It's something that I was asked to do for someone.

It was a dark Nightmare Night and Fluttershy was preparing for the "survival" of the night. But by the time she was about to go to her room, her door was knocking. She would normally yell at whoever is outside to leave her along but instead she found the courage to open the door. She was shocked to find Luna at her cottage. She welcomed her in. Luna noticed that she was still terrified to see her so she decided to make her feel better by giving her a nibble on the ear. Fluttershy suddenly feels melted inside and out come a blossom of warmth and peace.

Luna: Feeling better?

Fluttershy: …

It went so fast Fluttershy didn't know what just happen.
