The Substitute Bride and Her Blind CEO

Renee is newly married to Leander, an heir who is taken to be blind. The marriage was a strategic one, and she was put into it by the family that adopted her, in place of their own daughter Isabelle. Years of abuse in that house left her with a disability. Leander's blindness is an act he keeps up in order to look into how his parents died, and it let him watch, unnoticed, how Renee was treated there. They keep up their fronts through the intrigues of high society while starting a venture in AI technology together. Renee is in fact the AI master known as Nutien, and Leander turns out to be the mentor who has been teaching her for years. The venture brings out the secrets of a master who disappeared. The two of them test each other for a while before they come to trust each other, and once they do they work together to bring the villains to justice.
