There are plenty of reviews already explaining how awesome this movie but I'm still amazed. The plot is just so refreshing and different but not too complex. It's great! I think everyone would enjoy this movie regardless of age and preferences. To put it in short, it's a sweet love story of two people alone in this world. A woman who suffers from domestic violence and a mysterious boy who breaks into people's homes when they aren't around but only eats and sleeps there and retreats right after the owners return. The cast is amazing! The two main leads express themselves so beautifully without any use of words. I would recommend it to everyone. One of the finest Korean movies I have watched till date.
