Apparently, they don't know each other.
But they are both Koreans.
And they didn't live in Seoul, Korea for how many years.
While they were growing up, they live in Paris.
The both of them study there.
They have the same university in Paris but they don't notice each other.
Because they have never been classmates.
Until they graduated college.
Now they're all grown up and finished school, they plan to visit their home town and that is, of course, Seoul, Korea.
Will they see each other again?
Will they be destined together?
Will Seoul be the bridge to both of them?
