Apparently, Moon Ga-Youn (Ahn Soo Young) attended the same acting school as my cat. Whenever she is asked a question or to display an emotional response, she just turns her wide eyes and stares at you.
The rest of the cast aren't much better, though Yoo Yeon-Seok (Ha Sang-too) manages to go from abject despair to cracking half a smile. Sometimes.
As for this being a "realistic love story", I've lived a long time and have never managed to meet people with such a lack of communication skills or masochistic romantic involvements.
Thank God this is over this week. My cat liked it, though.
