Traveling Through the Book in the Extremely Cold Apocalypse, the Vicious Senior Sister Becomes Hot

I slipped into a book about the apocalypse and became a vicious senior's dog-licking and tool-man junior. At minus 70 degrees, the foolish author only stocked up on 100 dumplings, a ton of charcoal and a solar generator that was completely useless in the extremely cold apocalypse! The system forced me to follow the plot, and I did whatever the author wrote. According to the original novel, the vicious senior sister should have been in chaos and finally given up, throwing herself into the arms of a rich second generation and humiliating me severely. And my main mission is obviously to take revenge on the evil senior sister... But she became... Very wrong... System, please explain it to me. What does it mean that plot is plot and emotion is emotion? Forget it... See for yourselves!
