The Original Starfarer Quit, So They Dragged Me Over to Rule the Planet

[Apocalypse transmigration + interstellar + farming + slow-burn + leisurely pace] Lu Chu was grabbed by a zombie in the middle of the apocalypse. She'd thought she was done for, but to her utter surprise, she transmigrated. And it turned out the original owner of her body had brought her here. The original owner had taken her own life after the childhood sweetheart she’d grown up with died in battle, but she couldn't bear to leave her younger siblings behind, so she brought Lu Chu over to become the planet's ruler. Oh. The original owner had been the planet's ruler. But she didn't want the job anymore, so she brought Lu Chu here, gave her a new lease on life and a planet with a house. She had only one request: Take care of her younger siblings until they turned eighteen. Lu Chu agreed without hesitation. How hard could it be to look after a younger brother and sister? Could it possibly be harder than hacking zombies apart in the apocalypse? So the original owner went off to be reborn with her childhood sweetheart, while Lu Chu stayed behind to care for her siblings and inherit her planet. From then on, she spent her days farming, growing flowers, and raising the kids. Her two younger siblings were absolute little angels.
