Synopsis

The Shaderan family has fallen on hard times, and the avaricious and callous baron and baroness will stop at nothing to regain status. They favor their beautiful daughter Anastasia, hoping to marry her into wealth, while they treat the second daughter, Marie, no better than a servant. Years of abuse have convinced Marie that she is truly undeserving of love and attention.

On Marie's birthday—used as a ploy to showcase Anastasia—Marie meets Count Kyros Granado, who is immediately charmed by Marie and her knowledge of his culture. Believing Anastasia to be the one he fell for, Kyros proposes via letter. But Anastasia tragically dies on her way to marry him. Forced to take Anastasia's place, Marie becomes Kyros' fiancée, just as he originally intended. Although Marie terribly lacks confidence, Kyros gently helps her find her worth, awakening her to her own beauty and the true meaning of being loved.

After last season’s Too Perfect Saint, I needed my seasonal fix of cute girl having to overcome the trauma of familial abuse, neglect and insecurity while developing her sense of self, purpose and worth, with a sprinkle of drama and romance in there. Luckily, Betrothed to my sister’s ex didn’t make us wait too long. Despite this being the latest entry in an increasingly popular genre for adaptations, I think this is one of, if not the best of the bunch and it’s all thanks to the author having their characters act like real people! It’s such a simple, yet novel concept in animanga. Everyone ...

Mixed Feelings
Yeah, no. If you're here looking for your seasonal "awww, they're sooo cuuute", you went too far. This is a failed one. The only reason it gets a "mixed feelings" is because it went safe and there was no big damage.
(Also, the whole "recommended/not recommended" is wrong, because thats based on if you enjoy or not a piece of media (anime), whereas rating is based (or should be, because most still don't make the difference) on its objective quality. As in: the story, script, pacing, world building, design, animation, audio, VA, vfx, to name a few. And yes, thats important, because you can be high ...

TLDR: A visually exquisite experience weight down by shallow characters and an unoriginal story.

The show shines a light on interesting societal and interpersonal dynamics, but refuses to engage the topics in any detail to the point that they feel like set dressing. The male MC, Kyros, is a lord who employs the most capable people regardless of ethnicity/ nationality. Some of the positive sides of this approach, like diversity in cuisine, clothing, care products and procedures, are showcased but none of the conflicts that would arise from different upbringings and culture values are seen at all. Kyros himself is an ethnic minority and seems to ...
