Summary
My father gave me that name because he wanted me to grow up to be a strong and independent person. But perhaps my name was a curse… because for the parts that mattered most in my life, I was lonely and single. That was until…
“Dokja,” a man with a stern face is shown staring him down inside an apartment. His face looks as though it was carved by a master sculptor, every crevice and inch of his face a testament to perfection, even if that was partially ruined by the permanent scowl fixing his features.
Him…
Kim Dokja, on the subway, stared intently at his phone.

Summary
You’re a Deepspace Hunter. You fight monsters for a living.
But the real nightmare begins when you’re kidnapped, tortured, and turned into a weapon.
A week later you’re dumped in the N109 Zone with one command carved into your mind: kill Sylus Qin. Criminal mastermind. The man you were starting to fall for.
Except Sylus isn’t the monster they made you believe he is.
When he refuses to give up on you - even when you try to kill him - the lies in your mind begin to fracture. Surviving the aftermath is harder than breaking the conditioning, and healing is a slow climb through trauma, guilt, and scars that run deeper than skin.
Then the truth emerges: the people who broke you belong to Argent, a syndicate that destroys lives for profit.
And you and Sylus are going to tear it apart.
