My family lived under communism their entire lives. When they arrived in South Korea, they didn't even know how to use the bank system and ATM or the subway, nothing.
In North Koreans, the moment we are born, we don't know there's another life existing outside of our country. The regime always told us all the bad things about the outside world, describing America as full of thieves, all human scum, beggars, everyday people dying on the streets and hospitals.
Breathing in South Korea, even though the life here is not easy, makes me so happy. I feel that sitting in a coffee shop, having a cup of tea, and looking out of the window at the blue sky - this is happiness. Truly happiness.
We considered the Dear Leader our god. That's huge. He's more than our parents. I thought all of the world respected Kim Il Sung. That's why we were bowing to their pictures.
My favourite place in South Korea is Jeju Island: it's a tropical paradise with sandy beaches, turquoise waters, and the magnificent Geomunoreum lava tube system of underground caves.
My favourite Korean food is delicious black five-layered pork belly, cooked over a charcoal grill. And Jeju chocolate, in citrus fruits and green tea flavour, which is famous throughout Korea.
Among the difficulties I encountered, economic problems were the worst. I found that financial hardships could limit one's ability to realize one's dream, no matter how desperate and earnest you are.
Freedom means everything to me. It is the most essential right that every person deserves. Most people take it for granted, but not North Koreans.
I want to see reunified Korean peninsula, and I believe that the majority of Koreans in both countries want to see Korea become whole again.
We can have reunification if another power replaces Kim Jong Un. I don't know who it could be, but I hope and I believe another power, another person will be better.
I believe I'll see the reunification of North and South Korea in my lifetime and that defectors should play a role in rebuilding the country. In the long run, I want to return to North Korea, because that's where I belong.
Here in South Korea, I'm continuing to learn English in order to boost my prospects. When North Korean defectors try to get a job to stabilize their lives, their lack of English is a handicap. It was the same story while I was living in China. It took an enormous amount of time and enthusiasm to learn Chinese.
We always had power shortages in the country. I was living right next to the border with China, and it was the only country I could compare to my own. When I looked across the river, it was a completely different world - there were no people dying. It looked like a place full of colour, and that's what confused me.
Hyesan people have money, the most after those in Pyongyang, because it's near the border with China. Illegal smuggling businesses and Chinese trading companies operate there, so people can access outside products.
When I was growing up, my mum was doing illegal smuggling with China. Sometimes she would see a fortune teller for advice. One time I went with her: 'In your future, you'll be living in foreign country and eating the foreign country rice,' she said.
On a bus ride through China, my family and I had talked for hours before a police officer boarded to conduct an inspection. My mother and brother couldn't speak Chinese, so they pretended to be deaf and mute, and none of the Chinese passengers said anything, sparing us.
We were taught North Korea is a heaven. They told us how people in western countries die in hospital or have no money to study in school.
