Sometimes, it might be the best way to meet people - on the street!
Together with students who advocate for North Korean refugees, we took a street in Gangnam-station, the busiest place in Seoul.
We asked people's opinions on the unification of the two Koreas, and also conveyed our message supporting the people of North Korea.
For the short moment that people showed interest in us, we tried to raise our voices for people suffering in North Korea.
