But the pain is not just restricted to those on the peninsula as is the case for Manuela Schott who traveled from Germany to meet the father she never knew in North Korea.

Manuela Schott will always have a wound in her heart of not knowing her North Korean father.

Four months after her birth Schott had to be separated with her father who had to return back to North Korea after completing his study in East Berlin some 40 years ago.

Ever since, they were out of touch.

It was at the age of 19 when Schott first discovered the pictures of her father.

"I knew instantly that the pictures in my mother's diary was of my father. It was very shocking at first."

The 43-year-old Schott has been searching for her father and trying to find out his well-being but results were of no success, so far.

"I've asked the whereabouts of my father at the North Korean Embassy in Berlin but I did not get any answers."

Now after years she has come to South Korea hoping for a chance to meet her long-lost father by applying for the next round of inter-Korean reunions.

"I believe the only way I can see my father is when South and North Korea unify."

Schott says her one last wish is to ease her pain by calling her father, 'dad,' one day when they meet in person.
