Why Do My Brothers Like Me After My Sexual Transformation in the Apocalypse? ?

Apocalypse+Marriage Change+System emmm, I wrote this to commemorate a novel that was discontinued. I really like it... But the writing is not good. (Poor) ———————————————— One day, a virus suddenly appeared in the world, which could turn people into zombies, and the whole world was surrounded by zombies. Su Bai and Zhang Xiang were lucky enough to survive the virus. A few days later, Su Bai's hand was bitten by a zombie during an outing. "Zhang Xiang... Leave me alone! I will definitely turn into a zombie..." Su Bai shouted to Zhang Xiang. "Even if you die, I will still take you with me. Even if you have completely mutated into a zombie, you are still my good brother." Zhang Xiang wiped away tears. ... Su Bai changed "Top-up!!! How tall is this?" Su Bai looked down at her white hands and barren chest, "Why did I become a girl?! And she's a lolita!" "Ding~ Congratulations to the host for awakening the apocalyptic cute girl system (●'◡'●)" "I don't want your broken system, give me back my little brother ಥ_ಥ" "From now on, you are a girl~Don't think about the past anymore~" "No!!!!!!!!!" Su Bai was about to cry without tears. After a while... "Hey, I'm so handsome." ———————————————— Zhang Xiang: "Brother, you smell so good~ Didn't you agree to turn into a girl first to make your brother feel good?" "Go away! ヽ(≧□≦)ノ" ............
