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.
