The Person at the Center of His Replacement Bride

Every turn in His Replacement Bride lands on the same person, and the synopsis makes clear why they cannot step aside.

Under threats from her own parents, she was forced to put on the wedding veil and step onto the altar as a replacement. She expected a living hell with a monster.

Instead, behind the closed doors of the Wright mansion, she discovered the terrifying billionaire wasn't the beast the world feared, but a deeply wounded man fiercely protective of his own. Just as Seraphina begins to let her guard down and fall for her mysterious husband, the sister who ran away suddenly returns, demanding her 'rightful' place as the wealthy billionaire's wife.

That is the spine of His Replacement Bride: the people in the synopsis do not get to pretend the story started somewhere else.
