Lets start with the bad things: There is a lack of detail about characters and we dont get to know more about them, which makes them look kinda ''dry'' and not that sympathetic. The plot itself is kinda odd and unrealistic, but some people enjoy that and the others don't. Yet, there are many stereotypes that we all know from other films

Good thing is the acting and the atmosphere during the storytelling. I would say its a film to kill time if you have extra 2 hours but you wouldn't miss a big masterpiece if you dont watch it.

When a woman, Yoo-jin (Ji-Hyo Song), comes into Seo-jin's (Mu-Yeol Kim) life claiming to be his long lost sister, he becomes suspicious of her claims and true intentions with his family.

This film has both good and bad moments. Let's start with the bad.

There is a vague setup for the film and not enough individual character building. We just aren't given enough reason to care about what is happening with the characters to truly invest in whatever outcome awaits. The way the story has been setup lacks a direction for cause of doubt and it seems a bit rushed.

What I believe the film had going for it was a nice atmosphere. It was very tense even without having all the character building. It is what pushes the film forward. Also the acting was rather good.

I recognized Ji-Hyo Song from Wishing Stairs (2003), the third film from the Whispering Corridors series and I thought she did a great playing subtle nefariousness in her role. I recognized Mu-Yeol Kim from Forgotten (2017) and although he played his part well, he was overshadowed greatly by Ji-Hyo Song.

As far as the twist is concerned, some will like it because it is such a drastic twist while others will look at the screen sideways. It will come down to how you personally feel about it. I thought it was interesting but a bit lackluster. I personally wanted to see something with a bit more punch to it.

Overall the film held my attention but it wasn't the fast paced, intense thriller that I've come to expect from South Korea. Just a bit disappointed but still a decent watch.
