It was my first Korean movie and I'm so happy I watched it!
I only gave 5 ⭐ for Music because there wasn't like any music and 7.5 ⭐ for Rewatching Value, cuz you know what will happen and it's not as thrilling as watching it for the first time. Still rewatchable!
To the story:
The start of the movie throws you right into cold water with the first murder.
The female main character being deaf and mute makes it kinda easier for the murderer, which is pretty frustrating, but since she's pretty smart and knows how to deal with it, she always manages to get away from him.
The ending is cute with the brother and sister, the main lead and her mother at the sea, but I wished for the "villain" to get a more punishing ending than just dying.
Ending: I wasn't expending her stabbing herself to get back at him but she was giving off baddy vibes?
I recommend this one for people who like thrillers and want to watch and exciting movie with frustrating scenes and plots.
