While enjoying the surroundings in Barcelona, Choon hee(you) saw someone who will change her life and making her heart beats fast, but how can he tell that someone what she feels if she knew him and that someone doesn't really know that she exist?

Does her heart beats for the right guy? or its just her imagination that someday all things will fall to its place and she will be the one rejoicing?

And what will she do if she knows that she will be committing to a GUY that she didn't even know? Just for the sake of their company? Is she going to fight for the one she saw in Barcelona or will fall in love to the GUY?
