Mangjagui 2-bureul Sijakamnida

I've been possessed by a flawed, botched novel! With only one goal in mind: to return home, I saved the world from the Demon King and met my death... This cursed flop has a second part. Thankfully, it's a parenting story! I thought I just had to raise the original saint well, but the worldview is the same as Part 1, and I keep bumping into my companions. Not only have I possessed the worldview's worst villain, Adrian, but all of my companions in Part 1 have strangely turned evil. Will I ever be able to return to my original world?
