Yun Xi returned to the Mu family home to explain all the details of her treatment to the old lady. Mu Feichi had to go to the Presidential Palace so he called Jiang Chenghuan to escort her home.
As soon as Mu Feichi had left, Mu Chenhao, who was extremely curious about Yun Xi, came downstairs.
"Girl, I heard that you were my brother's girlfriend, right? You look like a minor."
"Who are you calling girl? I am older than you, so you should call me older sister." Yun Xi patted Mu Chenhao on the head. Mu Feichi acted so sternly in front of his half-brother, so of course she couldn't do anything to make him lose face.
Mu Chenhao squinted at her and smiled. His boyish, cheerful, innocent face was full of joy. He shouted at her, "Sister-in-law!"
"..." Yun Xi was at a loss for words.
Jiang Chenghuan leaned over, smiled, and patted Mu Chenhao on the shoulder. The two looked as if they were good buddies.
