The writer of '21st Century Grand Military Wife' even issued an apology amidst the historical accuracy controversy... It's upsetting, but let's hang in there, Wooseok!

Due to the controversy over historical distortion in our Wooseok's starring drama 'The Great Military Wife of the 21st Century,' writer Yoo Ji-won has finally issued an official apology following the director.
It seems the historical inaccuracy in the coronation scene—where they used the era name "Cheonse" and crowned the king despite the setting of an independent nation—became more of a problem than expected.
The director shed tears during the interview, and our Wooseok and IU also bowed their heads one after another, saying they hadn't examined the historical context of the work more deeply.
It is truly upsetting and regrettable that we were complacent about historical accuracy because it is a fantasy romance, but I feel relieved because our actor's feedback was so quick and serious.
Everyone makes mistakes, so I just hope Wooseok doesn't get too hurt by this and uses it as an opportunity to become even stronger!
