Just some stories. (short synopsis not title)
1) I went crazy after my childhood sweetheart married a mortal woman.
2) Someone came to the palace clamouring she was the real princess and I was the fake, but the emperor and empress insisted I was the real one.
3) The fake daughter begged me not to make her leave? Then I will make her die as the family's ghost since she wants to stay so much.
4) After my family won a war, they brought back a woman who helped them. My fiance broke off the engagement, saying he wanted a woman who can hold a sword, not a needle.
