From the moment she was born, my sister was the reincarnation of the Snake King's wife.
The villagers used the harshest means to make their sister a qualified snake king's wife.
When the Snake King came with the betrothal gift, my sister repeatedly warned me not to eat anything the Snake King sent me.
But before the snake king came to get married, my sister died suddenly and mysteriously.
Then something happened in the village.
Regardless of age, all girls in the village are pregnant.
