The Orphan

Jang Yunjin's life had always been defined by her bond with her older brother, Jang Yujin. Orphaned at a young age, they were thrust into a cold, uncaring world. Their parents' disappearance left them with no one but each other, and Yujin, being the older sibling, took it upon himself to protect her as best as he could. While Yunjin grew up with the hope of someday escaping their grim reality, Yujin's actions were often shrouded in mystery, leaving her unaware of the dark paths he was walking.

When Yunjin was 7 and Yujin was 10, their lives took a pivotal turn. A wealthy sponsor, recognizing Yujin's natural good looks, offered him a modeling career. At first, Yunjin saw this as a chance for a better life, believing it was a way out of the orphanage and into a world of opportunities. However, as the modeling gigs became more frequent, Yujin started to act strangely. He was often tired, distant, and would disappear for long periods.

It wasn't until Yunjin was 15 that she discovered the truth. One evening, after a particularly long absence, she followed her brother secretly and uncovered his involvement in an underground network. Yujin had been coerced into delivering illegal documents and drugs since he was just 10 years old. His sponsorship, once a hopeful path out of poverty, had slowly turned into a nightmare where his young age made him the perfect courier for the network's illicit dealings. To the outside world, Yujin was just another successful model, but in the shadows, he was a pawn in a dangerous game.

The discovery shattered Yunjin. She had always looked up to her brother, believing he was the one constant in her chaotic life. Realizing that he was tangled in this underworld left her feeling betrayed and scared for him. But Yunjin was no stranger to adversity, and she wasn't about to let her brother spiral into destruction without trying to help him. She knew that she had to act quickly before Yujin got further entangled in the web of crime.

Determined to protect her brother, Yunjin sought help in unconventional places. She started doing her own research and, through her tech-savvy skills, she discovered a hacker group known for exposing illegal activities. This group, known as "The Cipher," was made up of highly skilled individuals who specialized in digital warfare, data manipulation, and black-market intelligence. Though they operated in the shadows, their motives were not entirely malicious—they targeted powerful organizations and criminal networks, using their abilities to disrupt illegal operations.

At first, the group was wary of Yunjin, but her desperation and willingness to learn quickly earned their trust. She began working with them, using her newfound hacking skills to gather information about the criminal network Yujin had fallen into. As Yunjin honed her abilities, she also discovered a darker side of herself—an inner strength she never knew she had. She wasn't just the helpless younger sister anymore; she had become a key player in uncovering the truth and sabotaging the operation that had her brother trapped.

Over the next year, Yunjin became deeply involved with The Cipher, balancing her school life with her increasingly dangerous extracurricular activities. She learned to hack into secure databases, intercept communication, and manipulate digital footprints to track down illegal shipments and high-profile individuals involved in the network. With every piece of information she uncovered, Yunjin grew more determined to free her brother from the web of crime he had been forced into.

But as Yujin's situation worsened, and the consequences of his actions became more severe, Yunjin found herself in deeper than she ever imagined. The more she dug, the more dangerous the people involved became. With Yujin unaware of her secret life and her hacking activities, Yunjin had to navigate the dangerous line between saving her brother and protecting herself from those who would stop at nothing to silence anyone who threatened their operation.

As Yunjin entered high school at the age of 16, she was no longer the naive, hopeful girl she once was. The truth had changed her. She had learned to live in the shadows, a hacker fighting in the digital realm to save her brother from a fate she couldn't let him face alone. Yet, she knew the risks were only escalating, and that every step she took would bring her closer to a confrontation with the very people who controlled her brother's life.
