Kim Minjee never smiled. Maybe it was because she went through things that most people don't go through at the tender age of 6. Ever since her parents died, she moved in with her uncle. Her uncle didn't like it, but Minji started to fight. She was only 6, but she was already becoming a monster. At the age of 8, Minjee already became the best. She proved herself to be worthy of being the heir of her uncle's... company... Her uncle was worried. He felt as if he failed at parenting. He was letting her niece become this cold hearted girl, so he assigned her be bodyguards for people. Then at least she may meet new people. Soon Minjee was known as the Shadow. Minjee personally thought it was stupid, but many feared her. She was known as the bodyguard who was like a shadow, protecting with her life and offering no mercy to those who try to hurt the assigned person. But somehow, Minjee gets warped up into her best friends life, the one person she wanted to keep out of her dangerous life becomes the next person she is assigned to protect. Oh wait, it's not only one person.. it's a group.. They are called Stray Kids
