Lan Nuoyi, who has been determined to join the army since he was a child, finally made his dream come true in his sophomore semester and officially became a soldier. On the first day of reporting, he fell in love with military training instructor Xu Fei and secretly determined to capture him. After creating various encounters with Xu Fei, he finally caught his attention. In order to successfully enter Xu Fei's reconnaissance company, Nuo Yi worked hard on target shooting and various physical fitness. Finally, in the one-month final training assessment, Nuo Yi successfully entered the reconnaissance company with the first score among freshmen. He was dubbed the "Goddess Gunner" because he scored 99 points in the target practice assessment. After entering the reconnaissance company, given this first-come-first-served opportunity, Nuo launched a fierce pursuit of Xu Fei. Xu Fei, who knew that Nuo Yi liked him, did not respond to Nuo Yi's feelings and strictly demanded Nuo Yi during training. The frustrated Nuoyi understood Xu Fei's feelings for him through an accidental eavesdropping. It's not that he doesn't like No Yi, but because of the dangers of his profession, he doesn't want to hurt No Yi. Nuo Yi, who understood Xu Fei's thoughts, kept this innocent relationship in his heart and took a positive approach to daily training. During an anti-drug mission, Xu Fei was accidentally shot in the leg by a bullet. In order to successfully leave the country, drug lord Qiao Er took a local citizen hostage. In order to prevent the common people from being injured and to appease Qiao Er, Xu Fei offered to replace the hostage himself. Just when Qiao Er was about to evacuate, a bullet passed through the right side of Qiao Er's head. The sniper was No Yi. As Qiao Er fell to the ground, Nuo Yi, who was highly nervous, also fainted. In the hospital, Nuo Yi was still lying in the ward. As the door opened, Xu Fei's figure appeared at the door of the ward.
