I've been able to control my enjoyment of Korean Dramas for over 1 1/2 years, averaging one episode per day, except for an occasional two episodes (and a rare three episodes) on weekends.
Well, that changed over this year's Christmas/New Year's holiday. During the past three days I've watched the first 16 episodes of Iris (아이리스): 5 episodes on Saturday, 4 on Sunday, then 7 yesterday (Monday).
