If I was teacher, I would be chemistry and I would be the most dangerous teacher in the game. My notebooks would involve matching atomic numbers and atomic symbols of random elements to their corresponding element names from 1 to 118, hydrogen to oganesson, H to Og and vice versa, and have an empty periodic table at the top where you would have to drag and place the element to the correct spot on the table after matching. There will be posters of the periodic table of elements posted on the corridor walls for the player to quickly glance at for reference, but they cannot be removed from the wall, they're super glued so no one can try to cheat, peel them off and sneak them to class. I would already be ultra fast from the start because I can run a full mile nonstop in real life. Instead of getting close to the player and catching her, I would shoot the player with a pistol when I see her, and the first notebook would be in a different corridor from where I am so I don't shoot her right away when she comes out the door. I will chase the player at a very fast speed and I can shoot the player from all the way at the end of the corridor. The more element names, atomic symbols, and atomic numbers you get incorrect and the more elements you misplace on the periodic table, the more accurate and faster my shots will be, because I may be rusty and slow at first and miss a few times before improving the angrier I get. I can also use corrosive acids to dissolve away neodymium magnet-locked doors, which may take a few seconds to accomplish. As overpowering as I sound, I will run out of bullets, so I will retreat when I'm out of ammo to reload in a certain room, like how Viktor changes jackets in bathroom. I am most dangerous when I meet the player in the same corridor as her, but there will be a shield item where the player would have to pull it out and face it directly at me to block incoming bullets. The shield is brittle and may break sooner or later like the lock pick, so use it wisely and don't encounter me too many times. After the player collects all 10 notebooks, I will give the player one last chance to redeem herself. I would appear behind the player and carry her like h-teacher to the classroom with the final notebook. I will give the player a 15 minute time limit to LABEL EVERY ELEMENT ON THE PERIODIC TABLE FROM 1-118! Just labeling the name of the elements, no atomic number, nor atomic symbols, nor weight labeling, nor dragging them to their spot on the periodic table, and there's no specific order which you have to label them. The element will simply automatically pop up on their respective spot on the periodic table when you spell it correctly, I will not attack when you misspell, the element will simply not count nor appear on the table until you correct the spelling. When the timer runs out before all 118 elements are labeled, it's game over. Game will not let you pause during notebook to look online for complete modern periodic table, so it's better and more challenging if you actually took the time to practice and memorize periodic table of elements. When player wins final notebook, my closing phrase will be, "Good. You have proven to me you are not a complete dumbass like I though you were. Now fuck off from my floor before I throw acid in your face." This is just an empty threat not literally attacking the player with acid.
