Doomsday Wanderer Princess

Elysia had a hard time getting adjusted to the apocalypse, like anyone else would. She barely managed to survive by watching countless people suffer as she saved her own skin. Unfortunately, she was not the chosen one and eventually she also became infected. As she stared at the horizon in her last day as a proper human, her partner stabs her and she dies. How regretful, if she could go back, she wouldn't live like this, she would've tried to save everyone that she could. Even her partner.... But it's too late, she can't go back. -- Or so she thought! But how is it that she's suddenly back to before the apocalypse? What's....going on? And who's this handsome man that won't seem to leave her alone?? And that terribly annoying 'God' that sent her back here to clean up his mistakes just won't stop harassing her with calls. Is he her long lost mom or what? What the... Eh? What's that... You're giving me a system? No, no... go away! I won't accept this!!
