Noticing Qi Zihua's gaze, Bai Xuan's heart skipped a beat and said, "Zihua, let me introduce you, this is my sister. Sis, he is Qi Zihua."
"Hello." Qi Zihua smiled slightly and offered his hand.
Bai Xiao ignored him, "Haven't we met already? Let's skip the formalities."
"Indeed!" Qi Zihua withdrew his hand smoothly, not showing any sign of embarrassment, "Xiao Xuan, your sister is only a year older than you. Should I call her by name, or should I call her sister? We are not married yet."
The implication was that he preferred to call her by name.
Chen Wenxiang felt that Qi Zihua made sense. Bai Xuan reaching out to Qi Zihua was considered marrying above her station. Qi Zihua was older than Bai Xiao, and having someone call her sister now would seem rather unfair to Qi Zihua.
So, she said with a smile, "Just use her name, you can change how you address her after you two get married."
Bai Xuan furrowed her brows, a shade of worry crossing her eyes.
