A wealthy high school classmate of Yi Xiaoya who serves as the group leader for homework submission. She comes from a well-off local family and is popular among classmates. She harbors hidden resentment toward Yi Xiaoya, partly because Yi Xiaoya's beauty makes Xiao Caiyu look inferior when they sit together—classmates compare her to an ugly duckling versus a beautiful swan. She pretends to be friendly but her actions reveal her dislike. She plans to marry well through family connections rather than focus on academics.
