That is just what they do, korean dramas.
I've never (ever) followed one, regardless of how famous they were then. Suffice to say, the series I usually watch are occidental rather than oriental.
In this exam season, for the last three days to be precise, I succumbed to the lure of all things cute, and one complete season of them. Adorable leading lady, prince complex inflicted hero, male perfectly styled crowning glory (huar huar), melodious melody to spice things up, and in general, tear inducing plot or twist or whatever you name it before the happily ever after part.
Constantly I remind myself, get it out of your system quick, then back to your books. They are so addictive you cannot help yourself but be addicted ;).
The thing is, they make your tear ducts work overtime, involuntarily. The camera just have to be focused on their faces (which are full of emotion but with minimal facial expression!), then some music on the background.
And there you go- A Sobbing Nina. An Unstoppable Crying Nina.
Enough for now. Mari belajar! "Aja aja fighting!" teeheehee
