Watashi no Shiawase na Kekkon

Miyo Saimori was the unfortunate child of a loveless, arranged marriage. After her mother died, her father brought in his lover and other daughter, Kaya. From then on, Miyo's life was reduced to that of a mere servant. Even worse, while Kaya inherited the family's psychic abilities, Miyo had none—she was truly the daughter with no merit. After years of being treated like dirt, Miyo has learned to keep her head down, hide her pain, and obey every order. So, it comes as no surprise that she is arranged to be married to Kiyoka Kudou, a military captain rumored to be so cruel that he has driven away every one of his potential wives so far. From a painful upbringing to a painful marriage, that is the future that awaits Miyo—or so she thinks. Contrary to her expectations, her new husband is actually kind-hearted. What really awaits Miyo is a blissful, everlasting marriage full of happiness! [Written by MAL Rewrite]
