Since Hong Yi was standing with her back to her, Wen Xiao'ai couldn't see the expression on her face or the changes in her demeanor, but she clearly saw Hong Yi's back suddenly stiffen, followed by the lifting of her slightly bowed head.
Hong Yi slowly turned around, looking at Wen Xiao'ai with an expression she couldn't understand.
She opened her mouth and uttered a sentence, "…What did you just call me…?"
Her voice trembled, her finely arched eyebrows tightening and then relaxing, her expression profoundly odd, and her eyes conveyed a complex and difficult-to-grasp sentiment, seemingly tinged with a hint of excitement.
"Hong, Hong Yi sister… What's wrong?" Wen Xiao'ai asked, a bit puzzled.
She wondered whether calling her "sister" was incorrect.
Well… It seemed indeed incorrect; after all, she was five hundred years old.
Calling someone in their twenties "sister" might be taking too much of an advantage of them.
But… calling her "little sister" also didn't seem right.
