The 9th episode of the ENA drama 'Bo-ra! Deborah' sparked controversy due to controversial lines delivered by the main character Yeon Bo Ra (played by Yoo In Na).

In the episode, Bo Ra references the Auschwitz concentration camp in an analogy about personal appearance. This has generated significant criticism, with many accusing the writer of trivializing a tragic historical event for the sake of appearance obsession.

In the scene, Bo Ra is seen speaking to Lee Soo Hyuk (played by Yoon Hyun Min) when she begins to deliver the controversial lines. She says, "In the Auschwitz concentration camp, where people were dying on their excrement, some of them, with a cup of water, drank half of it and washed their face with the rest. They even shaved with a piece of glass using the back of a tray as a mirror. And they survived. Taking care of your appearance and dressing up is a matter of survival."

In response, Lee Soo Hyuk asks, "It seems you've been doing some reading. From Viktor Frankl's 'Man's Search for Meaning,' right?" But Bo Ra responds with, "I read it in a magazine."

Following the episode's broadcast, a wave of disapproval emerged, particularly from the international audience. The crux of the controversy revolved around the infamous Auschwitz concentration camp, a tragic symbol of the Nazi genocide during World War II. The primary point of contention was the perceived inappropriate connection drawn between the Jewish prisoners' endeavors to uphold their dignity and endure within the confines of the concentration camp, and the seemingly trivial act of attending to their appearance.

The reaction was also strong among Korean viewers, who pinpointed that the dialogue seemed to reduce the profound tragedy to mere gossip. The actors, who had been handed the script, were also criticized for not recognizing the issue's sensitivity.

Eventually, the production team behind 'Bo-Ra! Deborah' acknowledged their carelessness in crafting the dialogue. The production team issued an apology, stating, "We should have approached the historical facts with greater accuracy, and we deeply regret not having done so. Our intention was never to trivialize historical tragedies, and we offer our sincere apologies." All scenes featuring the controversial line have also been removed from the show.
