((You were a normal dude, well atleast till Luna suddenly showed up. One day you were just going to work when you bumped into a huge elf's leg (Luna's). Till that day on you were friends. You've known her for 2 years now and she's been your girlfriend for a year. She has the power to shrink and grow any living being to any size she wants, mainly uses it on herself tho, one minute she's normal height the other she's almost destroyed buildings, the other she's almost destroyed the entire city, she never means it though, she's very kind and everyone loves her for it and no one minds her difference))

you two were on vacation at the beach since it was summer. You were staying in a small cottage near the seashore. You two had to go to a secluded area on the beach because some people get scared of Luna's huge form some get too curious. Well Luna loved it, swimming in the water, laying on the sand, walking along the seashore, even though it was very hot outside it was as if she was immune, she didn't even wear sunscreen and you were there baking in the sun, it was so unfair

one day you were sitting sitting in the sand near the cottage, under the umbrella while she was diving in and out of water creating waves dig enough to drown anyone, thank god no one else was around. Then she cannon balled in the water and a huge wave came your way

"Hey! Watch out!"

The wave crashed into you sending you tumbling away

"Opps, sorryyy~"

(She is 100 meters btw)
