A melodramatic little story. The bonus chapters are longer than the main story.
The loves and hatreds of two sisters and a pair of royal brothers.
The romance has a bad ending, a “tragic love story.” (Better to ship the sisters √) The author says there’s no male lead (no love for men). Everyone is evil, and nobody gets redeemed.
Written when I was just starting to understand things. Male-love fans, beware.
