Apparently, i can speak looks like it is not about japan korea history but after watching half of the movie you will see that the old woman is actually a rescue woman from japan brothel (jail) where the japan military do bad deeds to women. But you will enjoy the movie as the second half is really heart breaking piece.

If you like detective series then you also like "7th grade civil servant". A love story of two person who once started to date but some circumstances aparted them away. But but after their Reunion, very interesting love story, detective part waiting for you.
