Total jumpscare scenes: around 6 scenes
Normal jumpscare scene(s): 3 (expected, slowly, far from the screen, creepy but heart-safe)
Mid jumpscare scene(s): 2 (unexpected ghost/scary characters appearance, slowly)
Extreme jumpscare scene(s): 1 (unexpected, fast, eyes to eyes with you, filling the screen, with SFX)

Pros:
- Apink's Eunji. Her acting is so good as always, I love her character in here.
- Nice plot twist.
- It's actually less scary, good for a scaredy-cat like me hohoho. Just watch out for an extreme jumpscare.
- The place they are shooting at really fits the theme. It builds a creepy atmosphere well.

Cons:
- I could say this is rated 16+ but no nudity. It would have been good if this movie has no romance aspect.
- Unsolved conflict.
- Somehow, there's a plot-jump. (Why this happened to this character? What is actually happening?).
- Unnecessary jumpscare (the extreme one).
- Some cheap CGIs are there.
