## Description
The protagonist, Hirose Yuzuru, was an ordinary student. 
He studied and worked on his part time job like everyone else, and was content with his monotonous life.
But there was just one thing he wished to change.
He wanted to get closer with Aizawa Haruka, the woman he fell in love with from the time he enrolled in school.
“Getting into a relationship with her, a teacher, is an impossible dream,” he thought to himself resignedly.
So he continued his unchanging everyday life along with his classmate cum Haruka’s sister, Aizawa Yuuka; and the junior at his part time job, Usami Akari.

However, one day his father started talking about remarriage and his monotonous life completely changed. He started living together with the woman he yearned for, and his relationship with Yuuka (who also started living with him) and Akari began to change too.

Yuzuru looked towards his new circumstances with hope and anticipation…
but the worst possible outcome was the only thing waiting for him.

## Characters
### Hirose Yuzuru (広瀬 譲流)
When I entered the academy, I fell in love at first sight with Haruka Aizawa, who was a new teacher at the time.  
Since then, I have continued to harbor feelings of admiration for Haruka for the past year.

He kept his unrequited feelings to himself and surrendered to a peaceful daily life, but after his father remarried, he began to look forward to a new life.

He does not join any clubs, but instead devotes himself to his studies, part-time job, and helping out at home.
Having lost his mother at a young age and with his father being a rather careless person, he has become quite skilled at household chores.

- **Gender:** Male

### Aizawa Haruka (相沢 遥佳)
She has a gentle and kind personality that matches her soft appearance.  
Her youthful playfulness also contributes to her popularity among students of both genders.

Since she was assigned to the school, she has been interacting with Yuuka, her younger sister, and their relationship is closer than that of a typical teacher and student. She is vaguely aware that Yuuka harbors feelings for her that go beyond the teacher-student relationship, and she doesn't dislike her for it.  
However, due to their respective positions, they have refrained from getting too involved with each other.  

While she welcomes her mother's remarriage, she feels both joy and confusion about living with Yuuka.

### Aizawa Yuuka (相沢 悠香)
She has a bright and honest personality and is blessed with good friends.
She can be a little overly affectionate, which often leaves Yuzuru at her mercy.

She has been friends with Yuzuru since their first year, and she realized early on that he had special feelings for Haruka.
As she observed Yuzuru, she began to become aware of him as well.
However, since their relationship is more than friends but less than lovers, she never voices her feelings.

While she is close with her good older sister Haruka, she harbors some inner complexes.

After school, they both work part-time at the same family restaurant.

However, her quiet and shy personality often leads to mistakes at work.  
As a result, she has become a target for the store manager, Shinsuke, to vent his frustrations.  

Through her part-time job, she has become close friends with Yuzuru, and they even eat lunch together at school.  
Yuuka, who is in between them, treats her like a younger sister.

### Kouno Kenta (向野 謙太)
He is currently unemployed and moves from one woman's house to another.

He is a liar and a frivolous person. He has been lying to his relatives, including Yuzuru's father, about his current situation. Taking advantage of the fact that his parents were away on their honeymoon after remarrying, he moved into Yuzuru's house.

He takes pride in his cooking skills, which are a result of his parasitic lifestyle, and specializes in stylish menus.  
He also has experience as an AV actor and is skilled in sex.  
He is careless about his relationships with women, but he has been able to charm those he likes with his bed techniques.

### Nimura Takeru (二村 哮)
He is a kind of old-fashioned, passionate teacher who is the butt of jokes among students, including Yuzuru.  
He has a serious personality, but he is unable to read the atmosphere around him and tends to interpret things in a way that suits him.  
This is particularly evident when it comes to women, as he is quick to misunderstand when someone is kind to him.

He is weak with alcohol and tends to lose control at parties.  
He often ends up having relationships with women due to his reckless behavior.  
Many partners leave him due to his insatiable appetite and self-centered, forceful approach to sex, but he remains unaware of this.

### Shimabukuro Shinsuke (島袋 信輔)
He is constantly frustrated by the poor sales of his store, which is a source of constant worry for him.
As a result, he often takes his frustration out on his part-time employees and even makes sexually harassing remarks.
In particular, Akari and Yuuka, who comes to the store to see Yuzuru, are his favorite targets.

As a single middle-aged man, he relieves his daily stress mainly through visits to sex establishments.
He prefers clingy play, which even sex workers dislike.
