Contorted (2021), A Ghost, Curse or Hallucinations ?

I avoid this film so many time and today is the day that I finally watching this Korea horror.
Should I keep saying this one is a horror film ? Very confusing.

Airing on October 07, 2021, I having a hard time to understand the whole film but luck for me, berkat pengalaman nonton yang banyak, I think I can know the film point but still wondering about the mask ?

Myeong Hye move to new house with her husband, a son and 1 adopted kid.
In the begin of film, we can see that she throw her own kid out from window, and the story change into her new life with 2 girl kid and 1 son.

Suffering, and always hearing a sound in the house, she tell her husband but didnt get a good answer.
When she finally open the door that supposed to keep closing, she suddently change and had weird personality.

The mask that she wear ? What is that ?
And the husband that finally change into devil ?
Everything is so no clear and lets say that the card name with “Savior Kim” name, what is the point then ?

Hui U is adapted kid after Hye losing her own kid.
Become the one that need to deal with her crazy step parent, she trying to asking help and keep seeing ghost, but its seem like nobody gonna help her until the film end.

We didnt get a clear explainations about the mask, and also there is no explainations about why Hye throw her own kids before ?

Everything in this film is so mess up, and that is very hard to be explain, but surely the film is highly not recommend because everything is really really mess up without anything clear !
