"I'm a traditional woman!"

The first time I heard this quote was in a 1970s time traveling/rebirth drama. The ML's brother had an affair with his mother's friend and the auntie said it every time she was accused of being inappropriate. I almost died laughing watching that and adore that auntie. The second time I heard that phrase was in a modern drama I no longer remember the plot of, but that same auntie played a background character and when she said her catchphrase I almost died a second time.

I watched a historical time traveling drama tonight and heard it for the 5th-6th time. Sadly, it was not the same auntie.

Does anyone have any idea where this started?? Istg I heard it in a regular cdrama recently too!
