From Gourmet Scans:
The blind Duchess regained her sight—only to witness her fiancé cheating on her that very day. Determined to take revenge on the scumbag and reclaim her family title, she made a bold move at the wedding—swapping grooms and marrying the infamous, devilishly handsome fugitive instead! Thus begins the tale of a Duchess and a wanted man, where marriage comes first and love follows later.
