A trace of confusion flashed in Qiao Nian's eyes. Puzzled, she asked, "Xiao Qi, why haven't I heard you mention Xiao Shi before?"
When Gu Qi heard Qiao Nian's words, he frowned and explained seriously, "Actually, I only found out that we might be siblings when I first saw her."
"Didn't you live together in the past?" Qiao Nian asked in confusion, although she already had a vague guess.
Gu Qi shook his head gently and said, "She used to live in Hai Cheng. She came to An City to look for me today. Only then did the two of us realize that we looked very alike."
Through Gu Qi's words, Qiao Nian roughly understood what had happened. It seemed that Gu Zhou and Gu Qi didn't know about the existence of Xiao Qi.
If she wasn't wrong, she should be Gu Qi's twin sister.
