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.

Мені сподобалось.
Я вже давно не переглядала романтики, але був настрій і мені попало це аніме під руки.
Звісно тут нічого нового чи ажіотажного немає. Але було мило та цікаво.
Також були дивні не логічні речі, але коли дивишся без очікувань і лишній претензій, - то це не надто заважає.
Мені сподобалось наскільки головний герой був відвертим та щирим у своїх почуттях.
В загальному досить мило.
Я б продовження подивилась. Бачу що ранобе досі випускають, то ж всяке може бути. Не знайшла жодного поки ранобе в перекладі, на англійській мові лише два томи, якщо зайде, то думаю будуть далі випускати переклад наступних томів.
Були доречі декілька моментів ...

Mixed Feelings
'Betrothed to My Sister's Ex' is the latest so-called Cinderella story from what we've had in recent years, namely, My Happy Marriage, as well as 'The Too-Perfect Saint: Tossed Aside by My Fiancé and Sold to Another Kingdom.' How does this fare?


§ Overview

Marie Sharedan is the maltreated second daughter of Duke Shaderan, whilst her older sister, Anastacia, is well-beloved.

Anastacia is supposed to be engaged with Count Kyros Granado. However, Anastacia met an untimely fate, so Marie has to be her substitute. Will Marie finally find the happiness that she was deprived of?

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 ...
