The Crow Princess of Fortune

Suisui is the young mistress of the Mystic Crow Clan, born lucky in a literal sense and able to talk with animals. The clan takes her for a jinx, whatever she says aloud being blamed for what follows, and she is abandoned at a mass grave as a child. She survives, and she turns up uninvited at a banquet in a marquis's manor, causing enough chaos to be remembered. At that banquet she saves Xiao Heng, Prince Jing, a man everyone avoids because he is under a curse said to kill those near him. She sets about breaking it. Her divine luck and a quick mind let her drive off what has been feeding on him, stay ahead of the people plotting against his house, and pull palace secrets into the open, including things about how he was cursed in the first place. The prince gets his strength back in stages. Suisui goes from the girl whose mouth brings misfortune to a princess people want near them for luck, and she works with her father to take back what their family lost.
