Tang Yichen expressed great surprise that Gu Zhiqi knew Yi Tingyu.
Knowing Yi Tingfeng, and also Yi Tingyu, and it seemed like they'd known each other for a long time.
He had known Yi Tingfeng and Yi Tingyu since they were kids, but why had he never met Gu Xiaoxi before, or even heard Yi Tingfeng mention her?
Hearing Tang Yichen's question, Su Yunling glanced sideways, giving Gu Zhiqi a look.
As Yi Tingfeng's little junior sister and also acquainted with Yi Tingyu, Su Yunling had a rough idea of what kind of little junior sister Gu Zhiqi was to Yi Tingfeng.
Gu Zhiqi looked up and glanced at Tang Yichen.
Sister Yu?
That must be referring to her Second Senior Sister.
Listening to this address, Tang Yichen and Yi Tingyu seemed quite familiar with each other.
