Betrothed to My Sister's Ex
Oshimeter
Synopsis
All her life, Marie Shaderan has been treated like a servant in her own home. Her parents burned through the family fortune and now pin all their hopes on marrying off her older sister Anastasia to someone wealthy. Marie gets the hand-me-downs, the chores, and the constant reminder that she's not the daughter worth investing in. Years of this have done exactly what you'd expect. she genuinely believes she doesn't deserve anything better. Then Count Kyros Granado shows up at a party that was supposed to be Marie's birthday celebration but is really just another stage for Anastasia to shine. Kyros, though, actually notices Marie. He's drawn to her honesty in a room full of performance. But because nothing can ever be simple, a misunderstanding sends a proposal to the wrong sister. This is a 12-episode TV series from LandQ studios, adapted from a josei light novel, and it leans hard into the slow-burn emotional payoff. The character work here is the real draw: watching Marie gradually learn she's allowed to want things for herself hits harder than you'd expect from the premise. The historical fantasy setting gives it a nice fairy tale quality without going full isekai. If you liked My Happy Marriage for the "neglected girl finds someone who actually cares" dynamic, or enjoyed the political family drama in Tearmoon Empire Story, this one's in that lane. It's quiet, romantic, and genuinely moving when it lands.

This is a great final episode and a good one to close this series. The plot reached its peak development in this episode. And finally, Marie shows just how much she has developed in this episode. Overall, this series is fun and interesting.
There's a glimpse of Marie and Anastasia childhood story in this episode. The pacing is not that slow and there's details about Anastasia backstory. And it's actually heartwarming to see the bond between Marie and Anastasia.
Marie's character development seems to regress in this episode. But glad she develops herself again after a thoughtful realization. This episode's full of drama and it's actually makes it quite exciting.
In this episode, the mystery surrounding Anastasia's death presents a dark and chilling atmosphere. The story of how her life ended is so terrifying. And then Marie's character get significant development. Furthermore, this epsiode ends in heartwarming moments between Marie and Kyuros.
This episode is so wholesome and heartwarming. The relationship between Marie and Kyuros is deepened. Also, their interaction is getting more intimate. Then, this episode becomes even more exciting because something happens at the very end.
The first half of this episode is full with adorable and wholesome moments between Marie and Kyuros. Their interaction also so cute. And then Mio's antics in this episode is quite interesting to watch. The cliffhanger at the end of this episode makes the next one even more compelling to watch.
The ten million pages that Kyuros wrote made a comeback, that was hilarious. To be honest, the parents did not deserve that well of a treatment becuase they were entirely disgusting to their daughters - good to know Cedric has a better life ahead of him. Very much the ending you'd expect, kinda boring but it was bound to happen.
I love Anastasia, you could already tell from the very first episode but this one confirms that she was also a victim of her parents abuse. But know she's free to do what she wants with her life as an artisan, she found her path and now she's also reunited with her beloved sister. I'm only wondering what will happen with the youngest brother, he was basically forgotten.
The appearance of a cute new character makes this episode more interesting. Also, their interaction is so adorable. However, the plot twist at the end of this episode makes the continuation even more compelling to follow.
Beautifully animated dance, a lot of character progress for Marie too. I wouldn't say the characters are particularly complex but it feels like they're a little bit more deep than just romance potential and being pretty, which is always very appreciated by people like me who are not particularly invested in this kinds of stories.
Marie's grandma was a feminist icon? Peak. Great episode, gut-wrenching in the moments where we get to learn the full story of what happened to Anastasia but balanced with the cuteness of that one puppy Kyuros scene.
This episode got me so happy with all the cutesy scenes and then it got all serious right at the end with a big cliffhanger. We finally get the big moment with Marie and Kyuros and we get a bit closer to understanding what's going on with Anastasia.
I think the serious investigation pairs well with the lighthearted date, writing-wise they don't seem to compete for attention. The Shaderan family is being very suspicious so that's a fun thread to follow.
The cliffhanger at the end is something you wont expect, I was very surprised about the turn of events. Kyuros is very cute as usual and I also really like his mom and how she bonded with Marie.
Very very cute episode, we get not only one but two small kisses. The animation for the sword battle was so much better than I would have expected from this anime, it was really fluid and well choreographed.
I really like the lighthearted humor of the chapter, it takes weight of Marie's low self-esteem. The introduction of the prince is also very fun.
This is an exciting and interesting episode. The interaction between Marie and Louis-phon is quite funny. Furthermore, Louis-phon and Kyuros's past is so hilarious and chaotic. And then Marie and Kyuros develops their relationship further.
In this episode, Marie develops her interaction with Mio. Besides that, Mio shows a great character progress in this episode. Overall, this episode is exciting and engaging.
The pacing in this episode is quite slow but there's development for the world-building. Furthermore, Marie develops her relationship with the castle's servants. And Marie is being cute wih Kyuros. This episode's atmosphere is heartwarming and wholesome.
I'm really enjoying Marie, she could use a bit more confidence but her knowledge and eagerness to interact with the servants is really nice and I like seeing her having to adapt to this new life and unlearn all the negative thoughts she picked up from her parents.
