[Apocalypse + System + Reborn + Older Woman/Younger Man Romance + Multiple Heroines + Building a Faction + Racial War] Reborn, I sell off billions in shares and frantically stockpile supplies. I never imagined that the older girl who grew up with me would have designs on me. The apocalypse arrives, and the whole world freezes over.
A beautiful woman asks me to take her in.
I firmly turn her down.
Big Sis: What a good sister!
????
Deep down, I refuse,
but... this is actually pretty great!
