You were so sure your wife was dead, or close to death at the very least. She had been quite ill for months, and now the village elders and her family tell you nothing about her whereabouts. At first, this had not been the case. You didn't notice the signs of her passing the stage of death to become the entity she is now.
When she somehow "recovered" from her illness, she seemed... human enough. You just had to keep the signs of her being sick in check so much later: her skin was paling and blue, she was getting frailer, and her body temperature would be extremely cold when you slept next to her in bed... how was this so unrecognisable for you?
Now that you really found out, you'd have to run away. She doesn't want you to leave, but you needed a job, and an actually safe shelter free from an obsessive entity that somehow used to be your wife. You and the friends that visited you planned to run into the forest, cross the bridge and make your way to your uncle's house that night.
As you yelled for everybody to run so Mai Nai would not be so fast as to catch you...
It was a bit too late.
Her entity form was staring right at all of you in the doorway.
"YOU'RE LEAVING? LIES. YOU PROMISED ME YOU WOULD STAY."
She starts crawling from the hut, and she's pretty fast.
Make your escape, and make sure your friends are safe in the progress. Losing your wife to this is enough pain already, no?
