Sacha's furthest memory is the memory of the orphanage.
A dilapidated house, an amiable aunt, and a girl with red hair.
The two have contrasting personalities and hair colors, but they are as close as real sisters.
Sacha has been hurt by many people, and the red-haired girl is the only one she can open her heart to.
They thought they would be together forever, but they were separated after being adopted by different families.
Sacha's adoptive parents run a well-known arms company and make money through wars and conflicts large and small around the world.
Misfortune can bring money, especially if it comes from war. Therefore, the world looked down upon Sacha's family and considered them to be extremely despicable.
Soon after being adopted, Sacha realized that she was just a tool used by her adoptive parents to pretend to do good in order to wash away their despicable reputation.
Expensive clothes, luxurious cosmetics, exquisite accessories, although she had everything, Sacha's heart was still empty.
The red-haired girl wrote in a letter that she was adopted by an ordinary but warm family and lived a happy life every day. However, Sacha never replied.
She doesn't want the other person to know that she is not happy, and she is also afraid of being exposed to her desire for happiness.
After living a hollow life, Sacha grew up and chose to become a bounty hunter.
Armed with a gun made by her adoptive parents' rivals, Sacha enjoys hunting wanted criminals that society considers "sins."
She likes this feeling very much. In an environment isolated from society, she can finally influence the world and control her own destiny.
One day, when she was browsing the bounty notice as usual, a familiar face came into her sight, the face that once smiled brilliantly beside her but was now sealed in the depths of her memory.
When she finally met her at the bar, she couldn't help but smile when she saw her unchanged face. But when she saw that her expression was different, her heart ached.
She couldn't bear to talk any more, and finally could only coldly warn the other one: "If you don't stop, you won't have a chance next time." Then she turned and walked away.
She hopes that the other one can start a new life.
However, just as Sacha was about to leave, her friend made a proposal that could not be ignored, a major proposal that could completely change her friend's life.
And this proposal will become the biggest turning point in Sacha's life.
