Betrothed To My Sisters Ex Review

Introduction

Adapted from a popular light novel and manga by Tobirano, Betrothed to My Sister’s Ex is a romantic drama premiering in July 2025. Produced by LandQ Studios under the direction of Takayuki Kitagawa, the anime presents a classic Cinderella-style tale, filled with misunderstanding, personal transformation, and healing.

Premise

Marie, the neglected younger daughter of a struggling baron family, has spent her life mistreated and overlooked, growing up without confidence or recognition. At her 18th birthday party, she meets Count Kyuros Granado, a nobleman who falls for her kind, sincere heart — mistaking her for her beautiful elder sister Anastasia due to a mix-up in names.

When Anastasia tragically dies en route to her arranged marriage with Kyuros, Marie is unexpectedly married off in her sister’s place. What she doesn’t realize is that Kyuros had meant to propose to her all along. From there, a delicate romance begins to blossom amid lingering grief, mistaken identities, and class pressures.

Characters & Relationships

• Marie is gentle, meek, and emotionally scarred from a lifetime of neglect and familial abuse. Her growth from self-doubt to discovering her own value forms the heart of the series.

• Kyuros Granado is noble and kind, initially misunderstood as cold and indifferent but ultimately revealed to be deeply caring and emotionally perceptive. His gentle persistence helps Marie gradually heal and open up.

• Anastasia, though largely absent from the present story, remains a major catalyst. Her absence shapes Marie’s fate and forces both the family and Kyuros to reevaluate their priorities and feelings.

• Mio, the loyal housemaid, and Liu-Liu, Kyuros’s mother, serve as important emotional anchors, offering Marie the support and maternal warmth she never received from her own family.

Animation & Production

LandQ Studios brings the romantic period setting to life with refined character designs by Akiko Satō and lush, atmospheric backgrounds. The animation is understated yet expressive, capturing quiet moments and charged conversations with sensitivity.

Director Takayuki Kitagawa emphasizes visual storytelling through close character shots, meaningful glances, and symbolic details — soft lighting, subtle gestures, and carefully composed rooms that reflect each character’s emotional state.

The series composition by Kenta Ihara ensures a thoughtful pace, allowing for both tender romantic scenes and emotionally weighty moments without ever feeling rushed.

Music & Tone

The anime’s opening theme, “Gesshoku” by krage, sets a romantic, slightly melancholic tone, while the ending theme, “Marie” by Myuk, offers a gentle, reflective ballad that captures the protagonist’s inner world.

The background score is light, leaning on strings and piano melodies that underscore the period romance atmosphere. It shifts effortlessly between romantic warmth and tension during emotionally charged scenes.

Themes & Tone

The anime leans into several timeless romantic drama themes:

• Cinderella Impression – The mistreated heroine narrative is subverted by granting Marie emotional depth and agency as she slowly claims her own identity and worth.

• Healing from Trauma – Marie’s journey is a sensitive exploration of emotional neglect and self-reclamation. Kyuros becomes a figure not of rescue, but of reassurance, allowing Marie to find her own voice.

• Mistaken Identity and Fate – The premise of identity confusion and forced marriage serves as a catalyst for deeper reflections on societal expectations, personal agency, and the nature of love.

• Class and Status – The story also subtly critiques the rigid social structures of its fantasy aristocratic setting, exploring how titles and birthright often overshadow personal merit and happiness.

Fan Reactions & Expectations

Early viewers have praised the anime’s heartfelt storytelling, warm visuals, and emotionally vulnerable characters. Many have compared it to other romance period dramas like My Happy Marriage, appreciating its gentle male lead and emotionally intelligent writing.

Some viewers note that Marie’s initial timidity can be frustrating, but most agree it serves a purpose in the narrative, setting up a satisfying arc of personal growth and empowerment.

Anticipation remains high for deeper exploration of Marie’s strained family dynamics, Kyuros’s personal history, and the inevitable societal challenges they’ll face together.

Final Verdict

Betrothed to My Sister’s Ex is shaping up to be a heartfelt, emotionally mature romance anime. With its classic period drama setting, sincere character arcs, and delicate balance of pain and tenderness, it stands out as one of the more emotionally grounded romances of the year.

Its strongest assets lie in:

• Emotionally grounded character work

• A gentle but firm male lead who values the heroine for her own self

• An atmosphere of quiet tension and hopeful healing

• Careful, expressive animation and direction

While the series walks familiar narrative paths, it does so with sincerity and warmth, offering a story of love that grows not from dramatic gestures but from patient understanding and mutual respect.

Recommendation

If you enjoyed anime like My Happy Marriage, Snow White with the Red Hair, or Taisho Otome Fairy Tale, Betrothed to My Sister’s Ex belongs on your watchlist. It’s perfect for viewers seeking a romantic drama with emotional depth, aristocratic intrigue, and character-driven storytelling.
