Beastworld's Fairy Guardian

This last year I have been reading a lot of manga and novels based on them where the Female lead falls into the beast world either while they are performing a ceremony to ask the beast gods for help or while she bathing and wakes up inside a lake with a man standing nearby or somehow in the forest being chased by wild animals and even one where a woman with plant-based superpowers wakes up in someone else's body.

So I thought to myself, what if she goes there intentionally after finding a journal from her ancestors that discovered the beast world but was never able to stay there as she was sent back to earth? She has powers, and it will be like a game with a system that will help her along the way. Keep in mind that this is a reverse harem story with characters inspired by what I have read.

When a female forms a spousal bond with a male, she will get a mark based on their animal form somewhere on their body depending on how much affection they have for that male. the first part of the story will contain more information on the characters (the main ones), the house that they'll build together, and more.

Just a reminder this is a story that I think is fun, not real and it is a reverse harem she will have quite a lot of spouses considering that she gets a period every month and the females there get it every 6 months. (You know for fertility)

Just a spoiler alert this story is totally fiction, so there will be things that on one side make zero sense like she is a fairy, so she will use her powers to help her people and herself. Like make winter boots or grow plants faster to be able to make winter clothes.

And as for the beasts, they will be able to transform parts of their body like their claws to walk barefoot even though it's wet or there is snow. And when in their human form, they will have their beast feathers showing like tails, horns, or wings.

This will be a bit of a mix of the novels and manga's ignoring the not so adaptable Bai Qingqing.
