Feifei: "What can't I do? I can cook, run a business, write books, solve crimes, do martial arts, act, sing... name it and I can do it!"

Feifei: "I live in the apartment next to you. Apartment 28."
"Huh? But there's no apartment unit next to mine?"
Feifei: "What are you talking about? Yes, there is. I just moved, maybe that's why you didn't notice."
"H-Huh... I guess so..."
Persistent suitor: "Feifei, do you have a boyfriend?"
Feifei: "I'm married. That's my husband."
Mr. 'Perfect Husband' a.k.a Ren JiYu grabs the pest pursuing his wife: "If you bother Feifei again, I'll destroy you."
Feifei drools as she watches her cool and manly husband threaten the other man. "System, isn't he just dreamy? But I think he shouldn't be so jealous, can you fix his stats a little?"
[*sob* Host, your husband is a cheat within a cheat! He won't let me fix him!]
JiYu grabs Feifei by the waist and lightly pecks her lips: "No fixing."
Feifei swoons: "Ok, whatever you say, darling."
