Lin Zhixia is Cui Ju's brother, a pale-faced and indifferent young man who leans against doorways and watches Bai An with a faint smile. He is initially perceived as scary by Bai An but shows a playful side, such as pushing her into a room and then helping her out the window. He is amused by her reactions and finds her childish. He keeps the books Bai An lent to Cui Ju and hides the note from his sister, displaying a protective yet teasing nature.
