I know that there are a lot like this, but the MC transmigrated into an otome game story I believe. There she was either a side character or a character who bullied the heroine. She changed and the ML fell for her. But the heroine is upset because it’s supposed to be a world for her. She has a small yellow bird that is like, light magic or something, that sacrifices itself for her.
I can’t remember anything else. Please help (=・ω・=)
