Because North Korean built itself up to be called the Hermit Kingdom, there was a lot of mystery surround what exactly was going on in the country.
There were reports of concentration camps, public executions, mass starvation, disappearances and even medical experimentations.
There has also been a lot said about leader Kim Jong-un and what he's like.
We've only really seen him reading a speech or inspecting factories - however this week we've seen a very different side to the Supreme Leader. And South Koreans have been shocked at what they've seen and heard.
Former South Korean army deputy commander Lieutenant General In-Bum Chun told BBC Radio 4: "Previously I had heard him read speeches for an hour or two, but today was the first time that I heard him speak.
"His voice sounded mature, genuine and relaxed, so it seems he wasn't the crazy man that some have depicted."
ABC News correspondent Bill Birtles wrote: "Visually at least, the beginning of this summit displayed a friendliness and warmth that seems decades away from the military parades and talk of war that overshadowed the Korean Peninsula just months ago.
But it wasn't just commentators who found the meeting between Kim and his South Korean counterpart Moon Jae-in interesting. Millions of Koreans were glued to TV screens and excitedly watched history being made.
South Korean citizen Lee Yeon-su added: "I can't believe I'm listening to the voice of Kim Jong Un. Someone I have only seen as a jpeg is speaking now."
Lee Seung-won said: "I thought he had a sense of humour. He's certainly different from his father's generation. I thought I would never see such scene before I die."
The two leaders made history yesterday when they met on the border between the two countries, shook hands and had a good ole chat. There were commitments to reduce and even eliminate nuclear armaments.
While their interactions were heavily scripted, there was a sense of authenticity and well-meaning behind the staged moments. Both stepped into the other's country - which, for Kim, has never happened.
There are some people questioning whether The Panmunjom Declaration for Peace, Prosperity and Unification on the Korean Peninsula will actually lead to genuine friendship between the two countries.
We'll never know what was happening when the cameras stopped rolling, but we can all agree that it's a hell of a lot better than a few months ago when all the big players were in a dick measuring contest with their nuclear weapons.
