Reborn in My Childhood

[A Note Before We Begin]: Since my ideas change over time, the outline for this story has changed. I'll be revising it from here on out... [The New Blurb]: This story is also known as "Saving the World Again Today" Most people who are reborn as children do it to build a fortune and become winners in life. Gu Yuanfang was already a winner from birth, but when she was reborn as a child, it was to stop the future Big Boss, a coldhearted, callous, and utterly deranged person, from destroying the world. Gu Yuanfang: "Although I was the last human on Earth to die, that's because I had a lot of meat on my bones." System: "And?" Gu Yuanfang: "Could we maybe switch to a different mission?" System: "Which would you choose, dying or doing the mission?" Gu Yuanfang: "You underestimate me! I'll do the mission, thanks!" [Reader's Guide]: The point of view is "unclear." The story is told from the male lead's perspective in the early chapters, then switches to the female lead's perspective later. Note: Her previous life was in the apocalypse, but this life is a sweet little romance with no connection to the apocalypse. The female lead is the future Big Boss. She has a warped worldview from childhood and an extreme personality: in other words, she's prone to becoming obsessive and turning evil. The male lead also lived through the apocalypse, so his personality is somewhat twisted. Neither of them is normal, so this is a story about two scumbags saving each other.
