Will Playful Kiss drop in ratings again?

Yesterday, MBC's Playful Kiss received double its normal ratings, but will it drop again? The sudden boost in ratings was due to the fact that there were no other dramas to compete against in that same time slot. The mega-popular 'Baker King' ended its run last week, and rival series 'My Girlfriend is a Nine Tailed Fox' was preempted by a movie. However, 'My Girlfriend is a Nine Tailed Fox' will be having�its final�broadcast today,�and will be airing two full episodes for the finale. Many are expecting Playful Kiss to experience a dip in ratings once again. On another note, 'My Girlfriend is a Nine Tailed Fox' is planned to have a sad ending, however, the staff have not been allowed to reveal anything about it.
