My Cousin Is Newly Widowed, the General Forced Me to Drink Concubine Tea

I am Jiang Luo, the princess of Zhaoyang County. I have a fiancé given by the emperor, General Song Li of Zhenbei. It has been three years since we got married, but I haven't seen him yet. Two days ago, General Zhenbei returned triumphantly, bringing back full glory. And... A newly widowed cousin. When we first met, my cousin cried and begged me to drink the concubine tea. Song Li stood beside me with a look of pity on her face. I pricked my finger with an embroidery needle. They say it is unlucky to have a red hijab stained with blood. It seems that this marriage is probably not going to happen.
