Even as a Zombie, I Still Want to Be a Mama's Girl

[Apocalypse + Strong Female Lead + Hoarding Supplies + No Male Lead]

On her way home for summer break, Ran Beibei gets infected with the zombie virus. She only wants to catch a distant glimpse of her mother from outside their apartment complex, but she arrives just as zombies launch an attack. [You can swagger all you want when you're out hurting people, but touch my mom and your life is on the line.] Without a second thought, Ran Beibei charges out.

Ran Aomei: "Beibei? How did you end up like this... Straighten your back. Stop slouching!"

Ran Beibei: "..."

Ran Beibei: "Mom, this is the fifth time we've had spicy blood curd this week."

Ran Aomei: "What will you do when you're hungry if you don't eat blood? Come on, have some more."

She awakens a System by accident and stays clear-headed despite being infected. How can an ordinary college student survive the apocalypse with her mother?
