Earlier, Yun Biyao was quite resistant to Lv Zhong, and absolutely wouldn't call him "brother-in-law".
Not to mention uttering "brother-in-law" in Lv Zhong's presence.
But now, she actually did so and so naturally to the point that Yun Shuiyao started to doubt whether her junior female fellow was replaced by someone else.
She had only left her for a few months? Her junior female fellow's thoughts had changed so much?
Besides being shocked, Yun Shuiyao was also infinitely shy. She hasn't yet established a real relationship with Lv Zhong. Being called so frivolously by her junior sister, she doesn't know how Lv Zhong would feel about it.
At that moment, Yun Shuiyao sneakily stole a glance at Lv Zhong, only to find him looking at her happily. Despite her usually cold and elegant demeanor, she then couldn't help but feel extremely embarrassed and quickly shifted her gaze away, her heart pounding and her face as red as fire.
