Female was 28 & Male was 48 at that time.20 years age gap.
Not correctly I can tell, but female was in her early 20s and male was in her late 30s or early 40s I guess. There must be around 15 years age gap in drama.
I liked it while watching initial first 2 episode, quite interesting. But as episodes go on, i lose my interest. Personally I didn't understand this series. I usually like series of this category but this was not my taste. It could be more interesting as concept was great. It didn't stand in my expectations.
You can watch here. If any chance subtitles don't show up , download eng sub online.
