Apocalypse: I Turned into a Girl and Got Thoroughly Trained by the Yandere Heroine

(Dual female leads + gender transformation + System + apocalypse + pure love + yandere female lead + petite, weak, submissive protagonist)

Qian Yao was sent to Blue Star by a truck, but why are there zombies on this Blue Star?!

One of them came right at her. Just as disaster seemed inevitable, Ye Nian'an appeared and saved Qian Yao like a goddess, leaving an indelible impression on her.

As Qian Yao was thinking, a voice sounded in her mind: “Ding! Congratulations, Host, you’ve bound yourself to the Cuddles System.”

“What kind of System? You’re saying that girl is the chosen one?”

Ye Nian'an felt an inexplicable attraction to the little white ball of fluff in front of her.

“Xiao Yao, you’re mine.” After spending a few days together, Ye Nian'an had already come to see Qian Yao as the most important person in her life.

“Master, haven’t I always been yours?” Qian Yao had already surrendered in her heart.

Still, Qian Yao really wanted to be the one on top. She was more than done with being the bottom.

The protagonist’s gender change happens very quickly.
