It's funny how you fall in love with the most unexpected person at the most unexpected time and it's amazing how can you fall in love with a person you didn't even notice the first time you meet them. After all, the thing about falling in love is not to force it. You just let yourself fall and wait for someone to be there to catch you. It just happenes so suddenly, you don't see it coming. It's just like rain, you can't predict it, but you can see the signs before it completely falls. 

And that is what happened to Hwang Eunbi, when she realized, although she profoundly tried to ignore the feelings, that she was falling in love with her opposite.
