Occasional family gatherings.
More than ten years ago, because of an influenza virus, the Gu and Mu families became friends. From then on, the two families often held family gatherings and the children of the Gu and Mu families became very familiar with each other.
At the parties, the children and adults would form their own little groups.
Yun Tianyou and Gu Linxi liked to brag about their sisters when they got together.
Yun Tianyou loved to brag about how cute Yueyao was, and how he was sure that she'd grow up to be a beautiful woman. Gu Linxi would not be outdone and would boast about how gentle and sensible Qianqian was.
On the other hand, Mu Yichen and Gu Chengze would get together and brag about how good they were at fighting.
When the adults sat together, the two men were the biggest braggarts. Occasionally, when Gong Jie and Hua Jin returned from Hurricane Island, they would join them in boasting.
