I need help to find a story:

MC dies and reincarnate as a bird. In a storm she falls to the ground and is found by a young boy who takes care of her. He becomes the hero of a goddess. She gets a curse that makes people go mad if they stay a long time in her company (I think). She later runs away and evolves. Her body is fragile but has a lot of MP (I think).

I believe the author is Birdie but it was a long time ago I read the story.

I found it! https://royalroadl.com/fiction/5323/they-said-i-could-become-anything-so-i-became
