It serves as a counterpoint to Ji Xingzhu's plans, frequently trying to keep Song Qingchi on track and make him famous rather than a laughingstock. It has telepathic communication abilities and can provide information about other characters, such as revealing that Wen Yajun is Ji Xingzhu's cousin. It often wails and sighs helplessly at Ji Xingzhu's schemes.
