THE BORROWED DAWN
The Forced Contract
Emii is a pragmatic woman from the modern world, living a life of quiet stability until she is forcibly drafted by a sentient, metaphysical "System." She is not a volunteer; she is an operative pulled across dimensions to rectify a tragedy. Her mission is to inhabit the body of Emii Lane, the "Cannon Fodder" heiress of the powerful Lane Dynasty, whose life is spiraling toward a pre-determined, gruesome end.
The Legacy of Betrayal
In the original timeline, the heiress Emii Lane was a disaster of her own making. Blinded by a misplaced need for validation, she turned her back on her blood. She trusted a circle of "Vipers"—rivals and false friends—while treating her own family with cold suspicion. By leaking corporate secrets and undermining her brother’s authority, the original Emii had unwittingly signed her family’s death warrant.
The Strategic Reversal
When the "Guest" Emii awakens in the heiress's body, the "Vipers" expect their puppet to continue the sabotage. Instead, they find a woman forged in a different reality—one who possesses a mercenary’s logic and a protector’s heart.
The Double Game: Emii must maintain the facade of the "clueless traitor" to lure the vipers into a trap, all while secretly rebuilding the walls of the Lane empire.
The Family Bridge: She must convince Krish Lane, the cynical and battle-worn brother, that his "sister" has finally returned to him. Through her brilliance, she earns his trust, and he, in turn, sharpens her into a leader.
The Twelve-Hour Tether
The mission is governed by the Twelve-Hour Tether, a brutal metaphysical cycle. Every day at 10:00 AM, the "Guest" Emii takes control, using mercenary logic to save the Lane Dynasty. However, at 10:00 PM, she is yanked back to her reality, and the Original Heiress regains consciousness. Far from a passive host, the Original Emii is a "cannon-fodder simp" who spends her nights leaking secrets and undoing the Guest’s progress. This creates a high-stakes internal war where the protagonist must outmaneuver her own body to prevent total ruin.
The Grand Finale
Over 160 chapters of high-stakes corporate warfare and metaphysical tension, Emii dismantles the vipers from the inside out. As the final strike against the Lane Dynasty approaches, she must execute a plan that requires the original soul’s cooperation and her own tactical genius.
The Resolution
The "Borrowed Dawn" concludes with the total destruction of the vipers and the restoration of the Lane name. Emii returns to her world, cleared of her own burdens and enriched by the lessons of leadership and love. She leaves behind a dynasty that is no longer destined for ruin, but for a future she helped them build.
