Sanemi, Obanai, and Tomioka's insecurities
Sanemi Shinazugawa
Sometimes he fears that his strong character will cause people to misunderstand him.
She is worried about not expressing her emotions well.
Due to his difficult childhood, he sometimes doubts whether he is enough to protect those he loves.
He doesn't like to show weakness in front of others.
Although he rarely admits it, he greatly values ​​the opinions of those close to him.
Obanai Iguro
He is very insecure about the scars around his mouth and usually covers them with bandages.
He finds it difficult to fully trust people because of his childhood experiences.
She tends to demand too much of herself and feels she can always do better.
She is uncomfortable drawing attention to her personal life.
He is worried about disappointing those he considers important.
Giyu Tomioka
Sometimes he feels that he is not good enough compared to other people.
He finds it difficult to express what he feels in words.
He tends to isolate himself when he is going through difficult times.
She is worried about becoming a burden to others.
Sometimes he doubts whether he deserves the affection or recognition he receives.
Despite these insecurities, the three of them work to overcome them over time, relying on the people they consider important and learning to trust themselves more.

Yes, Tomioka could also say "my wife," but it would be much less frequent than Sanemi. In a story set like yours, it would be like this:
Writing
What would each of you call me in private?
Sanemi Shinazugawa
He is the one who would use the most direct and protective expressions.
My wife.
Love.
Dear.
Princess.
My little girl.
Obanai Iguro
He is more reserved and would only use certain nicknames when they are completely alone.
My love.
My life.
Dear.
Treasure.
My wife (very occasionally, on special occasions).
Giyu Tomioka
He speaks little, but when he expresses affection he does so sincerely.
Love.
Dear.
My life.
My darling.
My wife (she would say it naturally and in a calm voice, especially when talking about you with someone she trusts or when they are at home).
The three of them would avoid using these nicknames at the academy to maintain professionalism and prevent anyone from suspecting their relationship. What would you call your partner?

Sanemi Shinazugawa

Sanemi would normally use direct and possessive nicknames (in the affectionate sense of an adult partner).

My wife. ❤️

My wife.

My little girl.

Dear.

Love.

“My wife” would be the one that would come most naturally to him, especially when he talks to other people about you.

Obanai Iguro

Obanai is more reserved, but when he's comfortable with you he might also use very serious terms.

My wife.

My love.

Dear.

My life.

Treasure.

He would probably say "my wife" rather than "my woman," because it sounds more elegant and formal to him.

Giyu Tomioka

Giyu doesn't talk much, so when he uses a nickname it has a lot of meaning.

My wife. 💙

Love.

My life.

Dear.

My darling.

Although he wouldn't say it constantly, "my wife" in Giyu would have a lot of emotional weight, because he doesn't usually express possessiveness or affection easily.

Who would have thought it?

🥇 Sanemi: “my woman” (all the time).🥈 Giyu: “my woman” (rarely, but very sincerely).🥉 Obanai: would prefer “my wife” or “my love”.

So yes, in your story there would definitely be at least two men calling you "my woman" and Obanai mentally correcting them.

Things they might say if they're jealous (Alternate History)

Sanemi Shinazugawa

When he feels jealous, he tries to stay calm, but ends up being very direct.

"Come here a moment, I want to talk to you."

"Stay close to me."

"I don't like it when someone tries too hard to get your attention."

"I just wanted to spend some time with you."

Although he tries to hide it, he usually looks for any excuse to be by your side.

Obanai Iguro

Obanai is more reserved and expresses jealousy in a subtle way.

"Have you finished talking to that person?"

"I was looking for you."

"I'd rather you come with me."

"We have some unfinished business, remember?"

Instead of arguing, he usually comes closer to you and stays by your side.

Giyu Tomioka

Giyu rarely expresses jealousy with words, but when he does, he is very sincere.

"Can we talk for a moment?"

"I'd like to spend time with you."

"I was waiting for you."

"Are you finished? We can go together."

His way of showing it is usually to silently accompany you and try to stay close to you.

In this story, none of the three react aggressively or try to control your decisions. When they feel jealous, they prefer to express it respectfully and seek to spend more time with you.

To them, you're practically their wife, and that's how they introduce you to their close friends, and so on.

Here's a version where the relationships ended badly and with a different ex for Sanemi.

Obanai Iguro
Ex-girlfriend: Reina Mizuno
Reina was a fashion designer. Although they shared a passion for design, their relationship became strained due to constant disagreements and a lack of communication. The breakup was difficult, and they both decided to cut off all personal contact. When they do happen to cross paths, they maintain a cold and strictly professional demeanor.
Giyu Tomioka
Ex-girlfriend: Aiko Fujimori
Aiko was a literature professor. Over time, misunderstandings and differences arose that neither of them could resolve.

Childhood and family environment

Sanemi Shinazugawa

Sanemi grew up in a very difficult home. His father was violent and subjected the family to physical and psychological abuse. His mother, Shizu, did everything she could to protect her children and give them love, but the situation was very complicated.

From a young age, Sanemi took on the role of protector to his younger siblings. This childhood, marked by fear and responsibility, led him to develop a strong, impulsive, and fiercely protective character towards those he cares about.

Obanai Iguro

Obanai was born into the Iguro clan, a family with extremely strict traditions and an oppressive environment. During his childhood, he lived in isolation with very little freedom, growing up under immense family pressure.

Those experiences left a deep mark on his personality, making him reserved, distrustful, and very disciplined. Eventually, he decided to distance himself from that environment to build a life of his own.

Giyu Tomioka

Giyu's childhood was marked by loss. When he was little, he lost his parents and was raised by his older sister, Tsutako Tomioka, who cared for him with great love.

Later, he also lost Tsutako, an event that deeply affected him. From then on, he became a quiet, reserved, and thoughtful person, though he always retained the desire to protect others and to value the bonds he manages to form.

Obanai Iguro
Obanai would think long and hard before deciding to have children. He would want to make sure he could provide them with a home filled with respect, peace, and trust. If he did start a family, he would be very attentive to the smallest details, teaching them patiently and ensuring they grew up in an environment where they felt loved and supported.
Giyu Tomioka
Giyu would approach fatherhood with calm and seriousness. Although he wouldn't talk much about it, he would show his affection through his actions. He would strive to be a patient, understanding father, willing to accompany his children through every stage of their growth, always respecting their personality and decisions.

The house was a spacious two-story residence with a basement, surrounded by a large garden and sheltered by tall trees that provided privacy. Its design combined a modern style with elegant details, creating a welcoming atmosphere for everyone.
First floor
Upon entering, one found a foyer leading to a main living room with large windows, spacious sofas, and a fireplace. To one side was the family dining room with a table for everyone, followed by a modern kitchen with a central island and a large pantry. There was also a library, a shared study, a laundry room, and a guest bathroom. From the living room, one could access a terrace overlooking the back garden.
Second floor
On the second floor was the enormous master bedroom where you, Sanemi, Obanai, and Tomioka shared the same space. The room featured a large bed, a sitting area with sofas, a television, a small coffee table, a spacious shared dressing room, and a private bathroom with a whirlpool tub, a large shower, and a spacious sink.
On the same floor were Genya's room, decorated in a comfortable and modern style, and Lili's room, elegantly decorated and filled with books, plants, and a reading nook. There was also a fully equipped guest room for family or friends when needed.
Basement
The basement was intended for family entertainment and hobbies.
The first area was a large games room with a pool table, a poker table, a foosball table, a giant screen for watching movies or sports, and a mini bar with non-alcoholic drinks, coffee, juices, and snacks.
From there you could access two private rooms.
The first belonged to Obanai. It was a studio dedicated to her passion for clothing design. It had several mannequins, drawing tables, sewing machines, shelves full of fabrics, threads and materials, a panel where she placed

The master bedroom was the largest in the entire house and was designed so that you, Sanemi, Obanai, and Tomioka could comfortably share the same space. It combined a modern and inviting style, with large windows that let in plenty of natural light and a view of the garden.

In the center was a huge, custom-sized bed, designed for the four of them. To one side was a spacious sitting area with an L-shaped sofa, a coffee table, a television, and a fireplace that made the atmosphere warmer during the evenings.

Each person had their own desk, bookcase, and wardrobe, but everything was part of the same room without partitions, creating an open space where everyone's belongings coexisted. There was also a reading nook, a small café with drinks and snacks, and a private balcony with furniture for relaxing outdoors.

The dressing room was spacious and shared, with enough room to organize the clothes and personal belongings of the four of us without needing to completely separate it.

The private bathroom followed the same style. It featured a large glass-walled shower, a whirlpool tub, a single, very spacious sink with a wall-mounted mirror that allowed several people to use it simultaneously, as well as ample storage for towels and toiletries. Everything was designed for practicality and comfort, while maintaining an elegant and relaxing atmosphere.

The room conveyed the feeling of being a true shared home, where every detail was designed so that all four could enjoy the same space without losing comfort or harmony.

You can describe it this way:
Your build is healthy and athletic. Although you have some curves and a few natural "rolls" around your abdomen and sides, these are subtle and harmonize with your figure. They don't make you look overweight; on the contrary, they make you look natural and balanced. Years of training in acrobatic gymnastics have given you strength, good posture, and excellent physical condition, so your body reflects both resilience and elegance.
Compared to many of your Japanese classmates, who tend to be very slender, your figure stands out for being more curvaceous and athletic. However, you've never considered those little natural folds a flaw; they're part of you and complement your appearance in a way that looks healthy and well-proportioned. And you have a little sister named Lili.

If you want to add it to the story, it could be like this:
Genya Shinazugawa
Age: 17 years.
Course: Same grade as you.
Relationship with you: Your best friend within the academy.
Relationship with Sanemi: Younger brother of Sanemi Shinazugawa.
Genya is a tall, athletic student. He has short black hair with a lighter streak and purple eyes. Although he seems serious and somewhat intimidating at first glance, he is actually a loyal and protective person to those he cares about.
With his other classmates, he tends to be reserved and only speaks when necessary. However, with you, he shows a more relaxed side: he converses naturally, helps you find your way around the academy, and makes sure you don't feel alone being so far from Colombia.
Despite being Sanemi's younger brother, their relationship is complicated. At school, they maintain a professional demeanor: Sanemi treats him like any other student and avoids giving him special treatment.
From the moment he learned you were an exchange student, Genya decided to be your friend. He showed you where the classrooms, the library, the gym, and the art club were. He was also the first person to make you feel welcome at Hashira Academy.
Although he respects that you are a very serious and reserved person, he understands that this is simply your nature and never tries to force you to talk more than necessary. Instead, he stays by your side when you need him, becoming your closest companion at school.

Sanemi Shinazugawa
Age: 29 years.
Subject: Mathematics.

Sanemi is a teacher renowned for his discipline and direct teaching style. He has short, messy white hair, grayish-violet eyes, and several visible scars on his face and arms, giving him an intimidating appearance. He usually wears a white shirt, black trousers, and a dark tie; when it's cold, he wears a black jacket.
In the classroom, he maintains an orderly environment. He does not tolerate interruptions, unfinished assignments, or disrespect. Despite his strong personality, he explains topics clearly and ensures everyone understands before moving on. Outside of class, he is less serious and tends to care about his students' well-being, though he rarely expresses this verbally.
Obanai Iguro
Age: 28 years.
Subject: Chemistry
Height: 1.62 m.
Obanai is reserved, observant, and a perfectionist. He has black hair with messy ends, heterochromatic eyes (one yellow and one turquoise), and his mouth is covered with bandages. He is also often accompanied by a small white snake named Kaburamaru.
He always dresses smartly: white shirt, dark vest or jacket, and black trousers. His classes are calm and organized. He likes students to analyze texts and argue their answers rather than memorize them. He speaks little, but when he does, everyone listens.
Giyu Tomioka
Age: 29 years.
Subject: Physical Education.
Height: 1.76 m.
Tomioka is a calm and reserved teacher. He has long, straight black hair, dark blue eyes, and a tranquil expression that rarely changes. He wears a navy blue athletic uniform with white details, sneakers, and always carries a whistle and a stopwatch.
In her classes, she prioritizes respect, teamwork, and effort over competition. She rarely raises her voice; a single look is enough for her students to understand.
