Maddie lives with her adopted father, so on weekdays, she works as an assistant for her father who is well known martial artists master in the underworld known as Master Li.
She would help teach and assist her master during his classes, so she would always have her guard up against everyone because as a woman she knows she is looked down upon by the other men there.
That's why she always strived to become stronger and never show her weaknesses to anybody except her master. He is the only person who knows about her past and saved her.
Ever since she devoted her life to be stronger so that she will never feel helpless and make sure that her master never regrets saving her that day.
Maddie would help with missions her master is associated with but he would never let her be in the front line and demand her to become a sniper.
This forced her to become excellent with guns and her shots always hit her targets.
But she never liked guns as she was always better at hand to hand combat. This is why no one will approach her during training sessions because they know they would just end up being defeated by her.
Some days she would teach a class alone because her master mysteriously leaves to train a wealthy client but she could never discover why her master wouldn't let her assist with this particular client.
Unbeknownst to her, her master was only doing this to protect her from the king of the underworld.
He knew that if he discovers about Maddie's abilities he wouldn't hesitate to claim her as his own.
He knows how possessive this man can be when something perks his interests.
But he doesn't know how long he can protect her, he always treated her as his own daughter ever since the day he saved her from getting murdered during one of his missions.
His team was ordered to eliminate her family because her father was unable to pay his debt.
When he saw how strong-willed and unafraid Maddie was against him, he knew there was something special about her so he took her under his wing.
Maddie was a very promising and talented little girl as a child and would learn things quickly.
Although when he first took Maddie away with him at the age of 6, she was very stubborn, despite that he was still able to teach her fighting skills and the ins and outs of the underworld.
At first, he was hesitant to introduce her to this type of life, but he knew that one day she would need to protect herself.
It was better for her to see how ugly this world is before she experiences the wonders of this world to prepare her for whatever comes her way.
