She used to be a demon monster but was reincarnated as a human girl. She was neglected and abused by the family she was born into. They forced her to manage the territory but to her humans are weak, so she made no complaints. Later she married a powerful noble who others call him bloody or something and on their wedding night he said he would never love her but to her it meant nothing because her thought process is too innocent due to her past life as a demon. She was malnourished for a long time so her digestion was bad so when they gave her a lavish breakfast she couldn't handle it. So, when they gave her light food she got sad but they said she can eat her favorite sausage when she gets better. Slowly he warmed up to her and he started feeding her and later realized she reminds her of the bird he used to care for. She told him she used to be a demon and would give him warnings like when she heard the cry of a bird monster that only cries when a natural disaster will occur and she told him a landslide will occur in 2 months. This is pretty much the first couple of chapters please tell me the title.
