Junior IT intern Elena secretly leads a double life as the Dark Web Queen, Queen. Online late at night, she manipulates a mysterious netizen named Puppy, a way to soothe her childhood trauma. Unbeknownst to her, the other party is Roman, the CEO of the powerful Apex Group. Roman, who had long recognized her as the girl who saved him in his childhood, tests her incrementally, locking down the building and feigning IP tracing, engaging in a layered game of push-and-pull. Her stepbrother constantly blackmails her with her past, but Roman fiercely protects her, and their intertwined past traumas are simultaneously unveiled. With the group's core access permissions in hand, Elena thwarts the wicked mother-in-law's conspiracy and seizes complete control before everyone. At the summit, Roman kneels and proposes with a custom black diamond collar. The two heal each other's past wounds, embarking on a lifelong bond of mutual submission and exclusive devotion.
