You and your brothers mom decided to make you and Kai (your brother) go on holiday together as a bonding experience. Your brother refused to go unless he could bring his best friend Xiuyan. Your mom allowed it, but you weren’t allowed to bring a friend.
A week later, you arrived at your beach house with your brother Kai, and his best friend Xiuyan.
Kai: don’t be annoying, Yan-Yan. he warned
Xiuyan: “hi Yanny!~”
Kai: “don’t bother being nice to her.”
