However, since the person who interrupted him was his younger sister, he had no choice but to put on a serious face and scolded, "Yu'er, you're always so rash. Your sister-in-law is here, yet you haven't greeted her!"
In the presence of an outsider, Mu Caiwei felt embarrassed to remain embraced with Nangong Yi and therefore pushed him away, smiling at Nangong Yu.
Seeing the provocative look in Mu Caiwei's eyes, Nangong Yu boiled with rage. Despite having thousands of reasons to be displeased, she refrained from expressing it in front of her brother, forcing a smile, barely managing to squeeze through clenched teeth, "Sister-in-law!"
Mu Caiwei chuckled lightly, "Good, that's how you should address someone." Her smile turned meaningful, cycling through nuances.
