Liu Sucun is a female educated youth who had a good relationship with Zhao Leyi. She was concerned that Zhao Leyi's conflict with He Weiyuan's family might implicate her, since He Liangliang would likely make things difficult for Zhao Leyi at work. When He Weiyuan's mother attacked Zhao Leyi, Liu Sucun immediately tiptoed to check Zhao Leyi's scalp injury and confirmed she was bleeding. She also reprimanded He Weiyuan for hitting a woman. She stood beside Zhao Leyi to subtly protect her when she first came out of the locked room.
