Betrothed to My Sister's Ex

Betrothed to My Sister's Ex is a fantasy romance anime blending heartfelt drama with a shoujo sensibility, produced by LandQ studios under the direction of Takayuki Kitagawa, with series composition by Kenta Inohara. Based on the light novel by Tobirana, the series weaves together everyday warmth and emotional depth within a richly imagined fantasy setting. Centered on Marie Shaderan and Kyros Granado, this adaptation brings a tender and immersive romantic fantasy experience to the screen.

In a world defined by rigid aristocratic hierarchies, Marie Shaderan lives a life far removed from the privileges her noble birth might suggest. As the second daughter of an impoverished baron's family, she is treated no better than a household servant, toiling in the shadows while her stunning elder sister, Anastasia Shaderan, basks in the family's attention and admiration — even on Marie's own birthday. One fateful day, a chance encounter outside her home brings Marie face to face with the distinguished Count Kyros Granado. However, a twist of misfortune sets their story on an unexpected path. When a sudden tragedy reshapes the family's circumstances, Marie finds herself bound by a marriage arrangement to the very count she once crossed paths with. Betrothed to My Sister's Ex follows this unlikely pair as a young woman who has known only hardship steps into a world of wealth and status she never anticipated.
