Esper Harem in the Apocalypse

"Yes." Rudy nodded. "I was running while yelling in the hallway."

"Rudy…" the principal read Rudy's school reports and uttered, "You are our best student. This school expects many things from you. All the students in this school admire you. You are their role model."

'That's what I used to think, until a few years later.' Rudy sighed inwardly.

"You should think twice before doing something. Because if you do something wrong, the other students will copy you," the principal added.

Rudy nodded and said, "I apologize for my behavior."

"There is no need to apologize."

"..."

'This is what happens when you study too much.' Rudy heard a voice in his head.

"Huh?" Rudy glanced around and thought, 'What was that?'

'Maybe I should tell him to take a break? Should I detain him for 2-3 days?' Rudy heard the voice again, but this time he was certain that it was the principal's voice.

'What's happening? I heard the principal's voice, but I didn't see him moving his mouth. Am I reading his mind?' Rudy wondered.

"Sir, can I go now?" Rudy asked obediently.

"Yes."

'You can take the rest of the day off if you want to.' principal thought.

'So I am truly reading his mind. But how? Was the experiment successful? They never said I would gain abilities. And what other abilities do I have?' Rudy wondered as he left the room and made his way back to his classroom.

He sat on his desk and resumed the class.

'This is the last period. I can't wait to go home and meet my mother. It has been two years since I last saw her.'

Rudy tried to read the minds of his classmates, but his powers weren't working.

'Is there a certain condition that triggers it?' Rudy wondered.

"Rudy. Rudy!" While Rudy was lost in his thoughts, the teacher called his name.

"Yes."

She pointed her finger at the mathematical problem on the whiteboard and said, "Can you solve it?"

Rudy looked at the board and read the problem in his mind.

Q- 8?i/ 3?2i. If the expression above is rewritten in the form a+bi, where a and b are real numbers, what is the value of a? (Note: i=√?1)

'Hmm~' Rudy hummed in wonder after looking at the problem. 'I had a hard time solving it in my previous life because it was tough. But now I can.'

Rudy walked to the board and took the marker from the teacher.

To rewrite 8?i/3?2i in the standard form a+bi, you need to multiply the numerator and denominator of 8?i/3?2i by the conjugate, 3+2i.

This equals: (8?i/3?2i) (3+2i/3+2i)= 24+16i?3+(?i)(2i)/(32)?(2i)2

Since i2=?1, this last fraction can be reduced simplified to 24+16i?3i+2/9?(?4)= 26+13i/13

Which simplifies further to 2+i. Therefore, when 8?i/3?2i has been rewritten in the standard form a+bi, the value of a is 2.

Rudy solved the problem within a minute.

"Done." He handed the marker to the teacher and sat back on his desk.

"Rudy, how did you manage to solve it? I haven't even taught that yet," the teacher asked, completely dumbfounded and surprised.

'Then why did you ask me?' Rudy sighed and answered, "I studied in advance, Miss Rize."

Rize was a young 22-year-old teacher working as an intern. She had beautiful pink hair and greenish-blue eyes. Many students had a crush on her due to her young age and intelligent persona.

Rudy and Rize had a bad relationship. They often called each other out to humiliate themselves. Rize was frustrated and angry with Rudy since the first day of school when Rudy called her out to point out her mistake. However, it turned out she wasn't wrong, and Rudy was forced to apologize to her.

Ever since then, they never missed a chance to get back at each other.

'I honestly missed this time of my high school. It was fun.' Rudy looked at Rize with a solemn look and a wry smile on his face. 'In my previous life, Rize got married two years later, and she was later killed by her husband on their honeymoon.'

'I will save you in this—'

DING~ DONG!

The school hours ended, and everyone started going home.

"Hey, Rudy!" Rudy's best friend—Eric, placed his hand on Rudy's shoulder and said, "Let's go play some soccer with the seniors."

That was a usual thing for Rudy, to play out with his friends and enjoy a very limited amount of his time.

"Not today, Eric. I have something to do at home."

"Alright! Then, I will see you tomorrow!"

Rudy left the school campus and took his usual route home.

SIGH!

He sighed and looked back at all his suffering from his previous life and muttered, 'I am not missing a single chance, this time.'

"Heh!" He remembered his conversation with Eric the last time he came to visit him at the hospital. "He was so awkward when he came to inform me about his wedding."

Eric got a job in an intermediate company and later married the daughter of the boss. Then, he was promoted and moved overseas with his wife.

"Now that I think about it, almost all of my friends got married. Though, none of them cared to inform me. It's not like I would have done anything, anyway."

'I didn't hear from my girlfriend once she moved out. I wonder if she also got a new…' Rudy clenched his fists and muttered, "I am the one who broke with her."

"Well, I will be meeting her again in the next semester when she transfers to the neighboring city."

Rudy was passing through a public playground where people around the block came to play. Suddenly, a tennis ball came flying at Rudy. It was about to hit his face, but he caught it with his hands even without looking at it.

"What the—!"

He had also gained super reflex ability.

"Hey! Give the ball!" a boy yelled out from a distance.

"They are not even apologizing…" Rudy threw the ball with all his strength, and it soared through the clouds.

"...."

Then, a soccer ball hit Rudy's leg. He glanced around to see some kids of the age of around 13-15 practicing soccer.

"Sorry! Can you please pass the ball?" a boy shouted.

'I do want to pass, but if it hits anyone, then they will probably die from the impact.' Rudy simply touched the tip of his shoe to the ball, and it passed through the goal net.

"...."

That day, Rudy realized that his second life was going to be more troublesome than he had imagined.
