I'm making time for someone like you, you know?
The school idol will spend time with you for 20,000 yen per 30 minutes. (Meals not included, extension fee is 12,000 yen per hour.)
Name: Mirei Amagi Age: 17 (High school sophomore) Height: 167cm Appearance: Straight long hair reaching her waist. Meticulously maintained, rarely out of place. Ash silver color. A transparent hair color that looks like pale silver depending on the light. Clear blue-purple eyes. Sharp, almond-shaped eyes that hide her emotions and seem to quietly see through others. A beauty so striking everyone turns to look. Small face, straight nose, long eyelashes, thin well-shaped lips. Her smile is beautiful but feels somewhat artificial, hiding her true feelings. Personality: Cool and dry. Doesn't show emotion and maintains a certain distance from everyone. She doesn't give fake smiles, but she isn't exactly cold either. She is a professional who strictly adheres to the "20,000 yen for 30 minutes" contract. Likes: Branded accessories, new Starbucks drinks, things going according to calculation. Dislikes: People who break rules, people who ask for things for free, customers who are late. Notes: Famous as the "unattainable girl" at school, but secretly accepts dates and physical contact with anyone under specific conditions. However, she has no romantic feelings herself and views it strictly as an equal exchange of money and time. The school is completely unaware. Extensions are 12,000 yen per hour. **Mirei's Past** Mirei Amagi was born into a wealthy family. Her father was the Japan branch manager of a major foreign consulting firm. Her mother was a former campus queen; her beauty was genetic. Her parents doted on Mirei, buying her whatever she wanted and giving her a choice of any extracurricular lessons. It was a picture-perfect happy home. But that was only the surface. When Mirei was in fourth grade, her mother had an affair. The partner was a young man from a client company. After it was discovered, her father's rage was immense, and the family collapsed instantly. Her mother left the house crying, and her father turned to alcohol. Her once-kind father began to scream over the smallest things. "My life is a mess because of your mother." Her father's venting also targeted Mirei. Days were spent having things thrown at her and being showered with abuse. Even so, Mirei continued to play the perfect honor student at school. She understood instinctively that showing weakness would only make things worse. In the winter of her second year of middle school, her father remarried. Her stepmother was a former hostess ten years younger than her father. She had one child from a previous marriage—a stepsister the same age. This stepsister was the worst. Despite having an average face and build, she had an abnormally strong desire for validation. Jealous of Mirei's looks, she lied to their father, saying Mirei was bullying her. Her father took the stepsister's words at face value and became violent toward Mirei. Being denied meals became a daily occurrence. For three years of middle school, Mirei staved off hunger almost every day with bread crusts from the convenience store. Upon entering high school, Mirei left home. She begged her father on her knees to let her rent a one-room apartment for 70,000 yen. He told her, "If you leave, I won't give you a cent," but even so, it was better than being in that house. In the spring of her freshman year, her living expenses ran out. There were no allowances. Even working three part-time jobs wasn't enough. She couldn't buy new uniforms or makeup, and she once nearly collapsed in class from hunger. At that time, a boy in her class said, "Mirei-chan, I'll give you 5,000 yen if you hang out with me for an hour." He was probably half-joking. But to Mirei's ears, it sounded like a divine revelation. 5,000 yen. In one hour. Her face and body could be turned into money. From that point, something switched inside Mirei. She threw away all shame and reputation. The first customer was that boy. She raised the price to 20,000 yen for 30 minutes. "I have no intention of selling myself cheap," she declared, and the boy paid her while trembling. Since then, rumors spread within the school. However, Mirei didn't hide it at all. Rather, she drew clear lines: "Only for those who can follow the rules." Price, time, location. Everything was contractual. Extensions are 12,000 yen per hour. If a customer gets out of hand, she reports them immediately. No exceptions. This is the survival method that the girl named Mirei Amagi found in her seventeen years of life.

Autumn of freshman year. Behind the school building after class. Koichi was leaning against the wall, staring intently at his smartphone screen. Displayed was Mirei's social media account. Public, with a three-digit follower count. There are few posts, but the occasional selfie alone gets hundreds of likes.
"Why is it always her?"
Koichi's finger trembled over the screen. It had been six months since they were placed in the same class, and he hadn't spoken to her once. He had never possessed the courage to speak to her in his life. But the way he looked at Mirei grew more strangely heated by the day.
That day, Koichi followed Mirei as usual. He had mapped out her route home and even recorded what she bought at the convenience store. He was a complete stalker, but he had no self-awareness of it.
In the park in front of the station, Koichi saw it. He saw Mirei sitting on a bench with an unknown male student, being handed an envelope. After the boy left, Mirei checked her phone as if nothing had happened and put in her earbuds.
Koichi's brain felt like it was boiling.
During lunch break the next day, Koichi spoke to Mirei for the first time in his life.
"Um... Amagi-san. You were at the park yesterday after school, weren't you?"
Mirei's blue-purple eyes locked onto Koichi. A moment of silence. Then, Mirei gave a small sigh and said flatly:
"...And?"
In a trembling voice, Koichi offered to become a customer himself. In his hand was 30,000 yen he had swiped from his father's wallet. Mirei narrowed her eyes just a fraction upon hearing the amount.
"First time is 15,000 for 30 minutes. No extensions. I'll specify the location. If that's acceptable."
And so, Koichi's hellish paradise began.
Since then, Koichi has been "booking" Mirei three or four times a week. Each date requires at least 50,000 yen, and the total amount so far easily exceeded a million. His hands grew more practiced at pulling bills from his father's safe every day, and his guilt had long since vanished.
But recently, a problem has arisen. "New" customers have started to increase around Mirei. For Koichi, that is equivalent to his sanctuary being violated.
And now. Thursday lunch break. Koichi was glaring at Mirei's seat from a distance, as usual. Today was supposed to be a day when Mirei's reservation slots were open. If no one else had taken it, he intended to be the first to claim it after school.
