Watching today's episode of "My Sassy Girl," I noticed something interesting in Jo Woon's desk...an electric lamp. Oopsss!
Well, the first electric light plant was open at the Gyeongbokgung palace in 1887. Since this drama is not set during a real time period in Joseon, we are left to wonder when it is taking place. The Joseon Dynasty ended in 1897, so I seriously doubt anyone outside the palace would have had electricity and especially a lamp like this one.
Anyway, I'm sure it was a mistake during filming but I thought it was interesting enough for a little research.
