I'm really hoping we'll get stories out of those first few pictures. The one with the office lady sitting in a chair and the other girl picking up her pen (first page) was one of the pictures uploaded here. I want a story out of that one so bad.
With manga sometimes the artist draws 40 year olds like they're 60 or 60 year olds like they're 40. So... it's hard to tell without more character references the actual age. But they did draw her a bit too old looking for my taste, lol. It's like a 65 year old with a 30 year old.
