Genshin Impact: I Became the Heroine, So Why Is Ying the Main Character?

When Lin Yue transmigrates into Yue, changing from a man into a beautiful girl, and arrives in Teyvat as the protagonist of this world, what choices will she make? But... she feels like something is a little different. (The author will change some details, so please don't mind. The early chapters follow the main storyline, so if you don't like them, you can skip straight to Chapter 40.)
