Date: April 7, 2026 (Tuesday)
Time: 1:07 PM
Location: Classroom 1-4
The lunch break was almost over. Albert was back in his seat at the back of Class 1-4. He looked to his left. The desk belonging to Himuro Leina was still empty. She hadn't returned yet.
He rested his chin on his hand and observed the rest of the classroom. It had only been a few hours since the opening ceremony, but the social ecosystem was already stabilizing. The forty students in the classroom were dividing themselves into distinct chunks.
In the center of the room, the extroverts had merged into a massive cluster. They were already exchanging LIME ID's and loudly coordinating a trip to a karaoke box after school.
On the outer edges of the room, the introverts remained isolated. They sat at their individual desks, reading books or staring at their phones, acting like the loud karaoke group didn't exist.
Albert analyzed the spatial distribution. It was basic social gravity. Mass attracts mass. People with high social energy naturally clumped together, while those with zero social energy were pushed to the perimeter.
On his right, Leo and Maya were sitting together, talking comfortably about their class schedules. But exactly once every minute, Maya would physically turn her body away from Leo, look at Albert, and ask him a question.
"Are you still hungry, Albert? I have some snacks left."
"No," Albert responded.
"Is the AC too cold for you, Albert? You look a bit pale," Maya asked, her eyes searching his face.
She was running a manual inclusion protocol. She was so hyper-aware of his isolation that she was deliberately interrupting her own conversation just to make sure he didn't feel left out. It was exhausting to watch. He gave her short, one-word answers to minimize her effort, but she kept doing it.
To give her an excuse to stop checking on him, Albert pulled out his smartphone and pretended to be busy. He opened his SMS inbox and clicked on the message from his dad.
He opened the full message to read it again.
*"I'm going to remarry. You'll be having a step-mom soon. She'll be moving in our house after we file the registration. Her name is Tendo Noriko."*
Albert stared at the screen. His parents had been divorced for over ten years. His father was always working far away and barely had time to visit home. The idea that he was suddenly remarrying was statistically improbable, but here was the data, typed out in plain text.
A heavy feeling settled in his chest. He was completely uncomfortable with a stranger moving into his house. His home was his only controlled environment—the only place where he didn't have to navigate social variables or pretend to be normal. Now, a completely unknown variable was going to be living under his roof.
But logic dictated his reaction. He was a minor. He had no financial independence, no legal authority over the household, and his father had already made the decision. There was absolutely nothing he could do to stop it.
He looked at the final sentence again.
*Her name is Tendo Noriko.*
First there was Tendo Shinji. Then Tendo Akari. Then Tendo Kyoko. And the crying girl behind the building, Tendo Ren.
Now, his future step-mother. Another Tendo.
The statistical probability of encountering five different people with the exact same surname in a single day is close to zero. Japan has over a hundred thousand surnames, and Tendo is not even in the top hundred. This level of data clustering defies basic probability. It feels like a system error, or a poorly coded simulation where the developer just copy-pasted the same asset to save time.
It was too much of a coincidence. The odds were so incredibly low that it actually made his chest feel tight, like looking at a math equation where the numbers suddenly stopped making sense.
Albert pocketed his smartphone. The accumulation of anomalous data—the handkerchief, the crying girl, his father's sudden remarriage to a 'Tendo'—was overwhelming. He needed to physically exit the environment to breath some fresh air.
He stood up. The scraping of his chair against the floor was louder than he had calculated.
Maya immediately terminated her conversation with Leo. Her head snapped toward him. "Where are you going, Albert?"
"Restroom," Albert stated.
The lie was the most efficient way to terminate the interaction. A biological necessity required no further social inquiry and provided an indisputable exit vector.
"Okay. Come back soon, lunch time is almost over," she said, returning her attention to Leo.
Albert exited Class 1-4. The hallway was still populated with active student clusters. He reached into his pocket, his fingers brushing against the folded pink fabric. He needed to deposit the item at the 'Lost and Found' to eliminate one of the unresolved variables from his day.
However, he lacked the spatial coordinates for the facility.
He observed the peer groups in the corridor. Engaging a fellow student required navigating complex social protocols: establishing eye contact, formulating an acceptable greeting, and risking dismissal or ridicule. The energy expenditure was too high, and the success probability was statistically unstable. To him, peers were volatile variables.
He scanned the perimeter and identified a male teacher standing near the stairwell, monitoring the hallway.
A teacher was a stable entity. Their occupational parameters mandated that they provide assistance to students. The interaction would be strictly transactional, devoid of complex social judgment.
Albert adjusted his trajectory. He stopped exactly one meter away from the teacher to maintain an acceptable social distance.
"Excuse me, Sensei," Albert said, keeping his vocal tone flat and respectful. "Could you provide the location of the Lost and Found?"
The teacher looked down. "It's in the Student Affairs office. Ground floor, West Wing. Go down this hall, take a left at the science labs, and it's the third door on the right."
"Thank you." Albert executed a slight bow and immediately resumed walking.
He mentally mapped the route: straight, left at the labs, third door.
As he walked down the hall, someone stepped out from a cross-corridor and ended up walking right next to him. It was a girl.
Albert stiffened. They were walking side-by-side, barely an arm's length apart. They were moving at the exact same pace.
He kept his eyes glued straight ahead. Even just catching a glimpse of her from the corner of his eye, he could tell she was incredibly pretty. He wanted to look, but he knew turning his head to stare at an attractive girl would instantly make him look like a total creep. So, he kept his neck perfectly stiff, stared at the wall at the end of the hall, and tried to walk as quietly as possible.
If I speed up, it will look like I'm running away. If I slow down, it will look like I'm trying to walk behind her.
Logic dictated that maintaining his current velocity was the only statistically safe course of action.
They reached the West Wing. Albert turned left. The girl also turned left.
His stress levels elevated.
They passed the first door. The second door.
Albert stopped in front of the third door. The sign read: **Student Affairs**.
The girl stopped at the exact same time, in front of the exact same door.
She turned her head and looked at him. Her eyebrows furrowed slightly, indicating confusion and a sudden awareness of his presence.
Albert's respiratory rate hitched. The circumstantial evidence was catastrophic. From an external perspective, he had perfectly mirrored her route from the main corridor all the way to an isolated office. The mathematical probability of two students heading to the exact same administrative room at the exact same second was incredibly low.
She thinks I followed her. I need to output a verbal explanation to neutralize the misunderstanding.
He opened his mouth, but his vocal cords refused to engage. The required social courage was entirely absent. The barrier was too high. He simply stood there in paralyzing silence.
The girl maintained eye contact for one more second before breaking it. She did not issue a verbal reprimand. Instead, she reached out and opened the door, stepping inside.
Albert followed a few seconds later, maintaining a safe distance.
The girl approached the front counter. An administrative staff member looked up from a computer terminal.
"Excuse me," the girl said. Her voice was steady. "Has anyone turned in a missing item today? I dropped a handkerchief."
Albert froze.
"A handkerchief?" the staff member asked. "Can you describe it?"
"It's pale pink," the girl stated. "With a small, embroidered floral design in the bottom right corner."
Albert's hand instinctively clamped over his pants pocket. His heart rate accelerated exponentially, hammering against his ribs in rapid, heavy thuds.
The staff member checked a small plastic bin on her desk and shook her head. "No, nothing like that has been turned in today. Sorry."
The girl let out a quiet sigh.
Then, the staff member looked past her. "And what about you?" she asked, looking right at Albert. "What do you need?"
The girl slowly turned around. She didn't say a word. She just looked at him. Her face was completely blank, but the pressure of her stare was suffocating.
Standing there with the pink handkerchief burning a hole in his pocket, Albert felt like the air had been sucked out of the room.

Subject: Math of Collision During Lunch Time Window
The handkerchief was lost during the morning. Because students are restricted to their classrooms during morning hours (unless the teacher allows anyone to go outside), the 1-hour lunch break is the first available opportunity for the owner to look for it and the finder to return it.
If both individuals searched at random times during that hour, the chance of them meeting would be low. However, because both individuals share the same priority—eating lunch first—their schedules naturally synchronize.
By eating at the start of the break, they both begin their search during the shortened time window immediately after their meal. This shared routine mathematically forces their timelines to overlap, making it highly probable that their paths will cross.
This temporal alignment is compounded by a forced spatial convergence.
The Student Affairs office functions as the official campus "Lost and Found."
It is the only logical destination for the owner attempting to locate the item and the finder attempting to return it. Because both individuals depart for the exact same location at the exact same time window, their paths are systematically forced to intersect.
The collision of the owner of the handkerchief and the one who found it (Albert) was not a coincidence. It was mathematically probable.
