Watched this without expecting much of a plot or one that has already been used to death so needless to say I was really pleasantly surprised!
The first 30 mins could be a little confusing and slow but it built the story and the last 30 mins deserves a 10/10!
You will know that this is a film without much budget but the casting was perfect. Both actors brought depth to characters who would be otherwise dismissed easily. The acting was great honestly, really heartfelt and made you feel for the characters as the story went. Seo Yeaji outdid herself and Kim Kang Woo was solid in delivering his role.
The twist, ah the twist! You can't help but keep thinking that you had guessed the plot correctly as it goes but really, its not what you think it is.
I would say try not think about whether you got it right or wrong as the film goes and let yourself be surprised by it.
Tissues are not necessary but highly recommended for the ending lol.
All in all a good watch and will probably be one of the few thrillers I see myself going back to.
