I really liked Anego too, and I'm glad you're enjoying it! I found it to be very well written and well-acted, especially Shinohara Ryoko! I'm barely out of my teens but I prefer female characters who are older, too :)

Shinohara Ryoko is in a whole bunch of dramas! So far the only one of hers I've really loved is Anego, but she also leads in 'Unfair' which I hear is very good, it's a crime thriller. Most recent one is 'Haken no Hinkaku', which someone on my flist recced to me.
