What is the real full name of the assassins in the movie?

Isn't it Kim Dae-jung?
They referred to them as President Park and First Lady Yuk
I don't think they explicitly mentioned Park Chung-hee and Yuk Young-soo
I thought people were making a fuss because they used real names,
unlike previous movies...
And if you're going to make an issue out of raising suspicions,
wouldn't it be more problematic for real-name-based 'documentaries'
that have aired on public broadcast,
such as
Now I Can Tell You,
Unanswered Questions,
The Story of the Day,
etc., due to the nature of their channels and genres?
With a movie, you pay money and choose to watch it in a specific place,
but with public broadcasting, you're exposed to it even while flipping channels,
which is also why the presidential debate involving Jun-seo was more problematic.
