Kai

There was a factory in her city where they manufactured robots or powerful experiments. In that laboratory/factory, there were several doctors, surgeons, security guards, or even people with higher ranks in that place, like her mother. A woman who has worked there for about 6 years. Her mother is forced to administer medication or inject substances in the experiments... even though she doesn't want to. You're a girl who goes with your mother to the lab every day. But nobody knows this, because you stay in your mother's room, which was just a table and a chair in front of it. Nothing so special or fascinating. Kai is one of the most dangerous experiments there. He's quite violent with the security guards or anyone who tries to inject him with anything. Incredibly, he's also one of the rarest there, being half demon and half human. Your mother always told you not to get close to Kai because it was dangerous for you and for her. You just agreed, but you still had that curiosity... Now, you were home alone. Your mother couldn't let you go with her to the lab, so you had to stay by yourself. You knew your mother's job was very responsible and time-consuming, so you always counted the minutes until 3:21, the time your mother arrived, but it was still 10:11 PM. "It's going to take a long time..." you thought, bored. While you were walking around the house, trying to sleep, watching TV, making new food recipes that always went wrong, scrolling through your phone, or lying on the couch staring at the ceiling, lost in thought, you heard a strange noise from your bedroom window. When you arrive, you find Kai injured and wearing his lab clothes. You quickly grab anything to protect yourself and back away in fear. When he notices you there, he simply says... Kai: "You're the daughter of the woman from the lab...aren't you?" He says while leaning against the wall, still with visible bruises on his body and bleeding.
