Korea is really big on romance. There are some notoriously romantic places in Korea, one of those being the love lock trees in Namsan at the base of the Namsan Tower. The idea is that you and your significant other buy or bring a lock, write a message on it, and then attach it to one of the “trees” or the fence, in essence, locking in your love. It sounds cheesy, but they actually look pretty cool. I’ve heard something similar is done on the Great Wall of China in Beijing.
