Lois, born with the heritage of the strongest creature in the world with wealth and thousands of years of lifespan as a dragon. However, facing unpredictable crises at every turn, not knowing when I’ll die—what kind of BULLSHIT is this?! It’s too unjust to just quietly die like this. Utilizing the future knowledge I have, I'll survive like a villain and give this story a twist!
