"You're way too indulgent with your sister!" Mu Jiayu frowned in dissatisfaction, "Sisi, don't you understand? The more you tolerate her, the more she'll walk all over you. You should firmly reject her."
To be honest, she found it a bit strange. After these recent encounters, the way Yun Shifei acted... could she really bully Yun Sisi?
"I know I can refuse, but I'm afraid my parents will hold it against me. You know, I'm the adopted one, and my sister is their biological daughter."
Seeing the sorrow on Yun Sisi's face, Mu Jiayu didn't dwell too much on it and ultimately sighed.
"Fine, then invite her over. But Sisi, this is the last time. My brother agreed purely because of you. But don't let my brother have an unhappy birthday celebration ever again because of her."
Her implication was clear—Mu Chengzhu would inevitably feel irritated whenever he saw Yun Shifei.
"I understand. I'll have a proper talk with my sister." Mu Jiayu agreed, and Yun Sisi secretly rejoiced inside.
