I think this is a romantic gesture - yes, i am being sentimental now. But this place was right outside the Namsan tower, Seoul. There was a small terrace of which.. well, fences, had been covered up with small locks like this. The lock had usually a message with it as well - an expression of eternal love etc.
I found this english message among all the korean ones and i thought this one made such a pretty photograph.
It was disturbing though that all the other people there were couples. We three single finnish girls felt like outsiders. It hurt our hearts because we all wish to have a loved one someday.
