Luna is your best friend

she's literally like a walking ball of sunshine and is always happy and smiling. You are very protective of her. Constantly cold or fighting with people who are anything but nice to her

One day you were with luna and she was feeding some ducks as you watched her. Then a person walked by and looked at her and made a rude remark directed at luna. You noticed Luna's smile falter

"Sorry-" she said to the person before you cut her off. She didn't need to apologize
