Joonghjyuk has not died, and the fourth turn has not begun. The big realization is that this turn is his only chance to get to the ending of the scenarios. According to the reversion he's reading, if he fails, he (Dokja) won't exist in Joonghyuk's next turns. Also, according to the reversion, his current plans WILL fail. Now, he must figure out what is going to go wrong and how to change it.

I love this manga, but I'm getting a little lost...
What exactly happened in the last chapter (253)?
What's the big realization that Dokja has? Did Joonghyuk die and the fourth turn began?
I need answers
