When it became obvious near the end, that this was just turning into a set-up for a sequel, I lost al patience with it. It is not nearly as charming as the first one was. This included a lot more violence - yes, the cells got violent and it didn't add much to the story. BaBi struck me as a nice guy but boring - he's a company man with not much personality of his own. I loved Woong's quirkiness, his ambition, his creativity. Babi was smooth and dull. And at the end, neither won Yumi, whom I decided was as boring as BaBi. I don't get why these guys are falling for here, there doesn't seem to be much to her other than - well, the cells. Another series that should have quit while it was ahead.
