Enemy general: "Little princess, I've destroyed your country. You can only stay by my side now. I'll build you a gilded cage and keep you as my canary. No one will ever take you away from me."

Underworld boss: "What, still trying to run? Xiao Ran'er, why can't you just behave and stay by my side?"

Villain at the academy: "Ranran, I was so happy when I found out you weren't a man, but a woman."
