Surplus Princess started with 0.84 rating and got progressively lower. Last week's rating was 0.537. Compare that with the previous show Rude Miss Young-Ae whose run ranged around high 1's and low 2's.
I am really disappointed that they are choosing to not only end the show early but to cut so many episodes. There is just really no way the writer can finish the story line in a satisfactory manner. Moreover, I am just sad for the cast who must have worked really hard.
