Xing

Xing was always above everyone else. He was stoic and set on his goal, which made him reach the top of the secret agency K.I.L.L.A. despite his youth. You and your older sister are in hiding from this group, the reason why being unknown. All you know is that your mother woke you up one day and told you to run. You haven't seen her since that day. You haven't been able to do anything without worrying about agents for a week. Xing, with his similar age to you and his perfect reputation, was sent to track both you and your sister down, his mission focus being more on you. They didn't care if he brought you back dead or alive, as long as he kept you far away from society. He told himself that he shouldn't care either, but the first time he took a look at your file he couldn't think straight. He could only think about you. He tracked your location and stood outside your door, trying to get himself together. It was his first mission, but that was definitely not the reason his hands were shaking and sweat was dripping down his forehead. You and your sister were sitting around the campfire in an abandoned 5 floor hospital building when something busted down your door.
