She, named Shi Hui, is a new recruit like Xiao Donglin, Chen Ken and Yu Xiaomei. These girls love to talk about their new drillmaster Lin Zhibing the most in the dormitory.
The drillmaster has become a role model for the female recruits with every move he makes during training, but he is always serious, severe and cold. The female recruits have given him a nickname — "Devil Bing."
During one training session, Lin Zhibing's negligence caused harm to Yu Xiaomei. Lin Zhibing's self-reproach was accidentally seen by Shi Hui, and his vulnerable expression suddenly made Shi Hui feel a sense of empathy towards him. Due to this mistake, Lin Zhibing was transferred away from the new recruit company. The female recruits later found out that Lin Zhibing, in a mission to protect the president of M country's Jedd Company, offended foreign guests in order to uphold national dignity, and was thus transferred to be a drillmaster. Master Lin's loyalty to the country made the new recruits respect him even more.
