People are in Star Iron, and the game begins with the unsheathing of Heavenly Fire.

However, Ron himself didn't care about any of this. He was neither blinded by the prosperity of the upper district nor ashamed of the mess in the lower district.

He quietly arrived at the medical school that had invited him to teach and quickly became a new teacher there.

Most of the students in the upper districts looked down on Ron, their arrogance typical of the upper districts, and they didn't think that a bumpkin from the lower districts was qualified to teach them.

Ron himself was too lazy to argue with these people and quietly continued his teaching.

The students were initially very resistant, and many even played pranks on him during his classes, hoping to discourage this teacher from the lower-class area.

However, after just a few days of teaching, the atmosphere in Ron's classroom changed drastically.

All the students were impressed by the professionalism of the doctor from the lower-class area, never imagining that one person's medical expertise could be so high.

Gradually, Ron's reputation grew, and students from all over the grade began flocking to his class. Eventually, whenever Ron taught a class, the entire classroom and even the corridors were packed with people.

Some of the older professors at Belloberg Medical School were undoubtedly fed up with this development.

They collectively filed a complaint against Ron, demanding that this country doctor from the lower district be sent back to where he belonged.

However, since the person who invited Ron was the president of the Berloburg Medical School, these complaints were naturally suppressed unilaterally by the president.

Meanwhile, Ron continued teaching and met a student named Wach in the process.

The other party is very talented, but has an extremely extreme mindset and is very arrogant. He always wants to break out of the framework of predecessors and design technologies that have never been done before.

Ron didn't pay much attention to Wach's ideas, only occasionally offering guidance on his medical research.

Meanwhile, he also heard Wach talk about his sister, a girl named Natasha, who was completely different from Wach and was a very insecure girl.

The other person always stayed alone in the school's infirmary, never daring to attend classes in the large classrooms, instead reading various books and conducting research on their own.

One day, Ron ran into Natasha and discovered that she had accidentally fallen down the stairs and twisted her ankle.

He then picked her up and took her to the infirmary for treatment.

"Natasha, student number 28, are you a student in Class A of the first year?"

"You...how do you know?"

Natasha was very surprised. She had never attended a class and was practically invisible to the entire college.

Ron calmly replied, "Of course, because I am your teacher, and I will not abandon any student."

"..."

Ron had no idea how much of a commotion his words had stirred in Natasha's heart.

All he knew was that from that day on, Natasha often appeared in his class. Although she still didn't fit into the classroom atmosphere, she was always the first one to appear at her desk.

A year has passed, and Ron's agreement with the principal is almost fulfilled.

He then prepared to resign from his teaching job and return to the lower district to continue his clinic.

Just then, he encountered Natasha again.

“Mr. Ron!” The girl hugged him tightly the moment they met, as if she didn’t want him to escape. “Thank you… I’ve always been timid and cowardly, unable to fit into the class. Nobody knows me, and even if they do, they just call me ‘Hey’ or ‘You’ or something like that. You’re the first person to call me by my name. I’m so happy, so…”

Ron's expression remained unchanged throughout, despite Natasha's excited and bewildered state.

He gently pushed the girl away from him and said slowly, "I'm resigning."

"Resign...resign?"

Natasha's face immediately showed a look of bewilderment.

She stared at the familiar man in front of her, bewildered. The words she wanted to say were stuck in her throat, unable to come out.

"Why?" Natasha asked, her face dark, as if she couldn't accept the outcome.

"I want to go back to the lower level."

Ron shook his head, offering no further explanation.

He didn't think his departure would have a huge impact on the girl.

So he completely ignored Natasha's reaction, turned around and left the scene, also preparing to say goodbye to the Belberg Medical School and return to his clinic in the lower district.

The next day, at his farewell party before leaving medical school, all his former students attended, and they all expressed their reluctance to part with him.

Ron didn't care about that. The only thing that surprised him was that Natasha didn't seem to be there.

Halfway through the farewell ceremony, someone in the audience suddenly exclaimed in surprise.

Natasha had somehow arrived at the scene and was lying on the ground covered in injuries.

Ron immediately went over, examined the wound, and then dismissed everyone else, taking the other person to the infirmary for basic treatment.

Why are you harming yourself?

Ron spoke directly to Natasha, who had just woken up.

"I……"

“You are right-handed, yet you deliberately used your left hand to cut shallow and weak wounds on your body. Although you bled a lot, none of them were fatal. This is a clear sign of self-harm.”

Unexpectedly, Ron immediately recognized that she had self-harmed. Natasha was initially confused, but then pleaded, "I want you to stay, teacher..."

"So you cut your own body so I could stay and heal you?"

"..."

Seeing the gloom and expectation on Natasha's face, Ron said coldly, "This is not a good method, Natasha. Even if you ruin your body, it won't change anything. I will still leave this school, and you will have to spend at least two more years here."

"Why?" Natasha's eyes were empty. "Teacher Ron said he wouldn't abandon me..."

“That was when I was your teacher.” Ron shook his head. “I’m not your teacher anymore.”

After saying that, he turned away indifferently, ignoring the tears streaming down Natasha's face.

"Teacher, no, don't abandon me! You're all I have left..."

“I’m sorry, I’ve already said I’m no longer your teacher… After all, before being a teacher, I was a doctor who healed and saved lives.”

Ron shook his head, closed the door to the infirmary with an indifferent expression, and left the scene, completely ignoring the despair spreading across Natasha's face.

He then returned to the clinic in the lower district, and his year at Belleberg Medical School felt like a meaningless dream.

And just like that, two years passed by in a flash.

His reputation as a doctor has attracted even more attention throughout the lower district of Belleburg, and the upper district has also gained a clear recognition of his superb medical skills.

Just then, he heard that the upper district had sent a medical school graduate to intern with him.

He calmly accepted the news.

It was a very ordinary day. He heard someone knocking on the clinic door, so he calmly went to the door to prepare to greet the new patient.

He opened the door and saw a young girl standing there. Although he vaguely recognized her, Ron's forgetful nature prevented him from recalling her identity.

So he calmly asked, "Who are you?"

"..."

Suddenly, this opening remark, spoken as if by a complete stranger, jolted the girl in front of him.

Then, a strange smile gradually appeared on her face, and she pulled out a syringe from somewhere and plunged it into Ron's skin.

"Teacher...we can finally be together forever."

Natasha's face broke into a maniacal and chaotic smile as she silently watched the man before her slowly lose his body temperature and turn into a cold corpse.

The last thing Ron saw was a smiling face with glistening tears streaming down its cheeks.

[This simulation ends]

[Achievement Acquired - Yandere Duo]

[Time and Space Simulator, welcome back next time!]

Chapter 88 Natasha's Yandere Transformation! I never want to be abandoned by you again, Professor Ron!

"So this really isn't some kind of yandere simulator?"

After watching the system's simulation, Ron's feelings were truly a complex mix.

He's starting to suspect that the root cause of the yandere phenomenon might actually be himself; otherwise, how could both Seele and Natasha have become yanderes after their simulations ended?

Now you know where the problem really lies, right?

[Note: The host is now immediately awarded the title of "Yandere Terminator." Keep up the good work!]

"You tm..."

Ron felt utter contempt for the system's opportunistic and sabotaging behavior.

But he was also well aware of the system's unreliable nature, so he simply ignored its antics and began to think about how to handle the situation.

His conversation with Seele made him realize that the simulations performed by the Time Simulator skill would have an impact on the real world.

Natasha probably already knows everything that happened in the simulation, and may even know that she was the one who saved the patient.

This raises two possibilities.

The first possibility is that the other person has come to terms with it and their emotions towards you are no longer as intense as in the simulation. The second possibility is that the other person has completely gone mad and become even more outrageous than Seele due to their yandere tendencies.

The second possibility seems more likely...

"No, we have to run away right now!"

Ron immediately realized that the best course of action he should take was to flee the scene, no longer daring to remain in the chaotic lower district.

However, just as he was preparing to leave and consider going to the mechanical settlement or the upper zone, the system suddenly sent him a new message.

[Temporary Mission - Savior of the Lower Beloborg District]

[Mission Brief: Integrate all forces in the lower districts of Beloborg and successfully prevent the Havoc Vanguard from completely invading Beloborg.]

[Mission Reward: Doctor's Class B Skill]

[Note: Integrating the two major factions in the lower Beloborg district—the Earthfire and the Mechanical Tribes—might start by resolving the mining crisis.]

[Note 2: I know you want to run away, but I also know you'll take on this task. Sometimes, the best way to fight fear is to face it. Go for it!]
