One of the most beautiful still sad movies I've watched until today.

I cried, I laughed, I smiled until my cheeks hurt. I was so angry about the injustice that I could die. But the thing is. It could actually be a "inspired in real events" movie because it sure happens. How people with disability can be discriminated and used. How justice can be evil and the criminals be guardian angels.

I just didn't liked the final event (don't want to spoiler ) but it's just real.

You will not regret if you watch this. A contrary. It has 10 out of 10 not just because you have Park Shin Hye in it (it's a plus haha) but because it's a great story that keeps you interested until the end, because has a incredible cast (Kal So Won is just amazing and Ryu Seung Ryong made real justice to his character. Park is Park. What more can i say?) And because it's all so well done that it's impossible not to like it. I waited three years to watch this. I sure regret it.
