My Happy Marriage (Manga) Vol 04

A Cinderella-inspired, slow-burn historical romance with a paranormal twist set in Taisho-era Japan! Miyo Saimori, the eldest of her clan and yet unblessed by the supernatural talent that graced her father and half sister, is sent off to marry into the Gifted Kudo clan. The young and aloof clan leader, Kiyoka Kudo, finds himself intrigued by this girl who stands worlds apart from the spoiled, social-climbing women who usually vie for his hand. All too soon, Kiyoka 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 wife worthy of the Kudo clan. Enter Kiyoka's older sister, Hazuki, who takes it upon herself to tutor Miyo-and tease Kiyoka along the way! Square Enix Manga
