Chen Jin’s younger sister, a junior high school student. She is mischievous and curious, frequently teasing her brother and trying to peek into his room. She has bright eyes and often uses exaggerated acting to call their mother’s help when Chen Jin subdues her. Despite her youth, she is tenacious and never gives up after losing physical play. She shouts “Mom! Brother is hiding something from us!” when she sees Chen Jin acting secretively. Her characteristic habit is kicking Chen Jin under the dinner table.
