Sitting in his room after coming back from school, with the situation having concluded uneventfully in the end, Christian was now staring at his phone.
He was monitoring the location of the math teacher live, tracking his every movement through the app, feeling a strange mix of curiosity and satisfaction as the day's events replayed in his mind.
It was a little early, a little far from the sun setting and the evening, but it seemed Christian was really destined to resolve the issue today. As the math teacher had gone to his usual bar earlier than usual.
Likely wanting to vent his frustration and forget that his teaching career had come to an abrupt end, the math teacher seemed to have sought refuge in the bar, hoping to drown his regrets by drinking.
Christian felt the situation couldn't be more perfect. With the math teacher off-guard and likely distracted by his own thoughts, even becoming drunk, it seemed like the ideal opportunity to move forward with his plan.
Now that his sister was at work, and since it was Friday, she would be home somewhat late. He would have ample time to finish everything before she arrived.
Then, looking at the time, which was now nearly 5 p.m., and wanting to be ready when the math teacher finished his drink, he started preparing himself.
Christian had thought a lot about this beforehand, what should he do to avoid being exposed? The math teacher wouldn't die from the beating, so there would be witnesses, after all. So, should he just cover his face entirely and be done with it?
In the end, the answer he came to was different, he should hide in plain sight, misdirecting everyone.
Christian started by putting on several layers of clothing to make himself appear somewhat fatter, and for the final layer, he wore a thin black jacket with a cap.
Then he began the most crucial step he had planned: coloring his hair.
He used a single-use hair dye to turn his black hair into a very eye-catching blonde and changed his hairstyle to one he had never used before.
He also put in color contact lenses, changing his green eyes to blue.
He then used his newly bought makeup to darken his skin, giving it a bronze-like appearance. He also put on the face mask he had bought.
Christian went to the mirror and looked at himself. But no matter how he examined it, he appeared to be someone completely different.
With his now wide shoulders and slightly bulky torso, his face looking somewhat older, and his bronze skin, blue eyes, and blonde hair styled differently to give him a more thug-like appearance, he truly looked like someone completely different.
Though it took some time to get ready, the math teacher still had not finished, so Christian began waiting for him to finish drinking at the bar.
Fortunately, the math teacher didn't make him wait long, and by the time the sun began to set, he left the bar.
Before departing, Christian added his finishing touch: a pair of very high boots that would make him appear at least five centimeters taller than usual, along with gloves to ensure nothing was left at the scene. He then opened the window of his room.
Perhaps the paranoia for carefulness was hereditary in their family, as evidenced by the security camera installed in front of the door, which had been put there by his sister.
So to avoid appearing on it, with his changes appearance, he carefully descended from his room, grateful that his physical training had prepared him well, as he encountered no problems.
He opened his phone to check the math teacher's location and reviewed the red areas he had marked, which had security cameras. Then, he began navigating his way through them.
Christian thought that maybe he was being overly cautious and that it might not be necessary. But after a moment's reflection, he decided it was always better to be safe.
Arriving near the turn where he was going to confront the math teacher, Christian began waiting, while keeping a close eye on his location.
But after a while, the math teacher suddenly deviated from his usual route.
Although Christian felt like cursing because his plan wasn't going smoothly, he still carefully watched to see where the math teacher might be going.
Seeing that it was just a normal residential area, with his house in the other direction, he found it a bit strange.
But he felt fortunate nonetheless, as he had also surveyed that area and identified a possible spot where he could still give the math teacher a beating at.
Seeing that he didn't have much time before the math teacher arrived, Christian started running, periodically checking his phone.
Because he was in a hurry, Christian didn't avoid the security camera this time. His house was a little far anyway, so as long as he took care on his way back, it would be sufficient.
Arriving at the very short and narrow street, he was heavily panting from running with all his might.
Christian walked to the side of the street near the corner and looked into the distance.
The math teacher was there, with a groggy gait and staggering strides, heading in the direction where Christian was waiting.
Christian felt the journey had been really long to get here, and he felt a bit sentimental.
The sound of a soft "tap" echoed through the quiet street.
As he watched the math teacher walk wobbly toward him, unaware of what was waiting for him, Christian felt like he could finally be done with him.
As the math teacher came next to him and gave him a look with his unfocused eyes, Christian, not wanting to wait any longer, extended his hand covered by the glove, grabbed the teacher's head, and covered his mouth.
While the math teacher began flailing his arms in resistance and glared at Christian with anger, he still had not come back to his senses.
