Female, Ji Changyu's younger twin sister. She is a pretty young girl in her final year of high school, with twin braids and a blue peter-pan-collar dress. She initially has a poor opinion of Xu Yao, thinking she is a scheming rural girl. She is cheeky and playful, once visiting her brother's northern military base during winter and huddling under quilts for two days. She is ordered to do twenty squats by her brother.
