I never watch korean movies , so It was totally by chance that i watched this and i totally not regret it.
I really liked it.
Amazing actors , specially the girl , she portrayed a crazy obsessed teenager SO well!
Though the ending could have been a little bit happier, i mean the family could have had a little bit of happiness going on there , but i don't know wether the teacher cried bc he loved her or bc she died?!! Left me a little bit confused , but I'm not complaining, i give it 10/10 , totally satisfied that this movie was the first korean movie I've ever watched.
