This is one place where you will not see me, ever, I hope. Maybe I'm just not romantic enough or maybe I'm not Korean enough to appreciate it.
In my opinion you should never do something like this in public. On the one side you're putting pressure on the poor girl and on the other side you are setting yourself up for a rejection to be seen by the whole world. There is also the idea that it really doesn't have anything to do with anyone else.
What exactly am I talking about? Just have a look yourself. Maybe you'll like it.
