My Happy Marriage (Light Novel), Vol. 4

A Cinderella-inspired, slow-burn historical romance with a paranormal twist set in Taisho-era Japan! A browbeaten and mistreated daughter is cast out of her home and sent to audition as a bridal candidate for the heir to one of the most powerful families in the land... Though the rumors make him out to be cold and haughty, Kiyoka Kudo quickly warms up to Miyo Saimori, the eldest of her clan but ungraced by the supernatural talent that blessed her father and half sister. Intrigued by the girl who stands worlds apart from the spoiled, social-climbing women who usually vie for his hand, Kiyoka soon comes to regard Miyo with affection. Kiyoka and Miyo make their engagement real and official, but Miyo still worries she lacks the training to be a worthy wife of the Kudo clan. Enter Kiyoka's older sister, Hazuki, who takes it upon herself to tutor Miyo--and tease Kiyoka along the way! Suddenly, a man named Arata Tsuruki appears before Miyo and Kiyoka. Who is this mysterious person, and what connection does he have to the enigmatic and powerful Usuba clan that Miyo's mother hailed from?
