Doki Doki Literature Club Plus - "SAVE THE DOKIS THEORY"

I'm excited for the new DDLC game that's coming out with new content set to take place before the literature club is set up: but a secret text in the original game hints at a unique plot that could take place in this game. Will you have to save the dokis from the events of the original DDLC? Are the characters even related to characters from the mysterious Project Libitina?
