Okey, I finished already. The end was rushed, but overall entertaining. It was a light reading. MC listened to me at the end and stopped being so childish, but I still have a complaint about writers and their need to ridicule strong female characters to make them somehow relatable.
The ML is total green flags and I understood I’m the one who has problems, because I miss Arhard (づ ̄ ³ ̄)づ

My only complaint so far is that MC knows that ML can't know that she is an angel/bird and, therefore, hides from him, but at the same time she expects him to know that the bird is her. Going around acting as if it was universal knowledge. Girl??? Are you really a bird with a bird brain?
Also, as I understand it, humans and angels practically have the same type of emotions, rationality and defects... So, tell me, why is this woman + 200 years old acting like an emotional little girl who doesn't know anything about interpersonal relationships?
And finally, I'm very annoyed by these modern writers who create infantilized female characters with military/fighting training, but zero brains to accompany that strength. You can't go to war being extremely impulsive, you are going to get killed or get everyone else killed. But they always masked it as "she's pretty and quirky LOL, she's also OP asf, but dumb! can’t have it all!”
