People say: Twins are divided souls.
Sister - loved by everyone, gentle and beautiful, devoted to love, tolerant and letting go.
The younger sister is lively and smart, dares to love and hate, but she even chooses to quit in order to repay her sister.
Sister - I have no worries about food and clothing, but I never knew I had a sister.
My sister——my soul has been living in my sister's body for 15 years.
The story takes place in the Tang Dynasty, where humans and demons fight. The union of man and devil, right? Is it wrong?
