Teacher!Prussia X Yandere!Reader - My Senpai

It was 5 am and you already waited at the entrance of the school. No one was here yet and meanwhile you waited you looked at your phone, opened the gallery and stared at the pictures of your crush...Gilbert Beilschmidt.
He was one of the sexy teachers from this school and you made so many pictures of him meanwhile you had lessons with him, history lessons of course. Even you shouldn't make pictures and focus on class, you had to make pictures. You printed all of them out and made posters of it. You even have a shrine, you called it the Gilbert-Shrine. You collected everything of him. Once he lost a coin, you quickly grabbed it and when you got home, you put it to the shrine. You also have pictures there, a handkerchief, an apple and more things. But the most important thing was, that he used one of them or just touched it. For you, everything that had to do with him, turned to gold, at least in your opinion.
But also, your life was dangerous and it wasn't always that easy to be close to your senpai and then there were also other teachers that got in your way.
Then finally you saw his car, it was already 7 am, seems like you forgot the time meanwhile you stared down to your phone. Your heart beated fast in your chest. You hid behind a tree and after he made his way inside the school, you tried to follow him inconspiciuous. He was so handsome, you thought and escorted him to the teachers room. Now he was safe from other pupils, but not from the teachers, but to go in, wasn't allowed either. So you took your things and sit down quietly in the classroom. The other people never understood your love, they even made fun of you, but all you cared about was Gilbert Beilschmidt.
The bell rang and you looked at the door, then to the clock. You waited and waited meanwhile the other played something and made pranks, even scissors flew through the air. You sighed, stood up and went to the door. Someone screamed at you: "(Y/N), do you want to tell Mr. Beilschmidt about it again? Be glad that he is not here. So we may have a free hour". Two girls ran to you and tried you to bold you back. Unfortunately you couldn't break out from it, but you still fought against them until Mr. Beilschmidt entered to classroom and screamed: "What's that? Let (Y/N) go immediately!". The two girls let you go and sat down on their seats. You bowed infront of your teacher and said: "Thank you Mr. Beilschmidt" "No problem". You blushed and also went back to your seat. 'Mr Beilschmidt saved me', you thought and listened to his talking and tried to make more pictures of him. He was also sexy when he had those glasses on. Some pupils noticed that you were obsessed with him, they even whispered so loud that you could here it: "What's wrong with her?" "She is such a pain" "Who needs her anyway?" "She just tries to get close to Mr. Beilschmidt". You sighed, they could never understand, but your duty was to make your senpai happy, to escort him inconspicuous and to watch him if he is safe. You could never forget yourself if something bad would happen to him. When class was over, Mr. Beilschmidt went out and you hid behind some cabinets and watched him until he was at the teachers room again. Unfortunately you had to live with it that you can't protect him further after this class, because he also had lessons in other classes too.
The rest of the day you thought about your teacher and couldn't focus on the further lessons. Also the other teachers were stupid anyway.
Finally school was over, but you couldn't go home yet, you had to wait until Mr. Beilschmidt also had finished his job. So you waited on a bench for 1 hour longer and then you finally saw him again. Your heart couldn't beat normally and you slowly walked behind him and watched him until he sat down in his car and drove away. You smiled and thought: 'Now you are safe from the others here in school, but...what if something happens like a car accident?' You shook your head and told yourself: "Don't even think about something like that. Remember, Gilbert is awesome, he can't die easily". You look at the direction were senpai's car drove and you sighed and whispered: "Notice me already".

~~~~~~~~~~~~~~~~~~~~~~~~ Next day ~~~~~~~~~~~~~~~~~~~~~~~~~

Like always you were very early in school, escorted your favourite teacher, which probably also thought that you must be crazy and then went to your class. Actually it was a calmer day for you until you saw in a break one girl talking to him. You didn't know this girl, but she seemed very suspicious. You narrowed your eyes and tried to hear their conversation. You thought that they talk about a homework or something, but for you that was still enough. She was too close to your senpai, just a bit too close for your sense. You tried to remember her face, her hair, her clothes, everything. You made a picture from her, you smiled and thought 'You will see how sweet revenge can be'. After your classes, you went out of the school and hid. You waited for this girl and when she came out with her friends you went to her and said: "Hi, it's important, I need to show you something and it also has to do something with you". She just looked at you and then to her friends and answered: "But I don't even know you" "But, please, it's really important, I found something out...about you and just you are allowed to see it and I can show you the place", you told her. She looked confused, but then said "ok". You leaded her to a place where no one could see you. She asked: "And what is here?" "You will see soon", you answered and stabbed her with a knife until she laid there unconscious. "Don't go near to my senpai", you said and left her body there. You went to the school gate again and noticed that her friends were already gone, better for you. Your next step was, to wait until Mr. Beilschmidt went out of the school and after a few minutes he did. You stared at him and he finally he met your gaze and said: "Should I bring you home?". Your heart beated faster than it ever did and you whispered: "Yes". He smiled and you went with him to his car and you told him were you live. Now he knows your adress, it was your lucky day, until the next day came.

~~~~~~~~~~~~~~~~~~~~~~~ Next day ~~~~~~~~~~~~~~~~~~~~~~~~~

You were already in your classroom and wait for lessons, actually history lesson. Mr. Beilschmidt entered the room and wasn't happy at all. That broke your heart and you asked: "What happened Mr. Beilschmidt?" "The headmaster found a dead pupil in the garden. She were killed yesterday after school", Gilbert told the class. Everyone was in shock and one guy answered: "Maybe it also happens to us". You wanted to laugh, but you hold it back and were silent, you just thought: 'That happenes when you go near to my senpai'.
After a while it was break time and you sat on the bench and watching pictures of your teacher until those girls from yesterday saw you and one of them screamed: "it was her, you killed my sister" "I did nothing", you said and wanted to stare at the pictures again. Another one said: "You are crazy. I saw you yesterday" "I...I did nothing", you lied and Mr. Beilschmidt came to you and the others and asked: "What's wrong?" "She killed my sister yesterday", one of them said and another added: "I even saw her yesterday. She stabbed her with a knife". You looked at Gilbert and said: "I did nothing, I swear, it wasn't me" "Liar", the other girls screamed at you. Mr. Beilschmidt grabbed you and went with you in a room and locked it. You smiled and thought: 'Seems like he like it rough'. "Why are you smiling?", he asked you. You remained silent and just looked at him. He grabbed your shoulders and said: "What's wrong with you (Y/N)?". You blushed, he said your name, then he added: "I know it was you!" "What?", you whispered and looked into his red eyes. He looked angry at you and you looked at the ground and he said: "It wasn't the first time you killed someone, right?". Gilbert went to the desk, took out some newspaper and showed it to you. "Do you know these people?", he asked you and you shook your head. "Then you maybe know this picture", he said and showed you a picture of you in the newspaper and yelled: "You are already suspicious, since the beginning". "I'm sorry, senpai", you whispered really quietly. "What?", he said and you answered: "I'm sorry, Mr. Beilschmidt" "I guess a sorry won't do it. How many people have you killed and why? Tell me!", he screamed the last part at you and you closed your eyes and said: "I don't know" "You don't know how many you have already killed?", Gilbert yelled and you just wanted to hide somewhere, but also you kinda enjoyed that little game. "And why?", your favourite teacher asked. You looked up at him again and smiled: "To save you" "To save me from what?", he wanted to know and you answered: "To save you from the others. What if they hurt you? Or .... no I don't want to think about it" "You are totally crazy (Y/N). I have to call the police", Gilbert said and you screamed, fell to the floor and hugged his legs: "Noooo, please, not the police". But actually it was already too late. Other teachers heared your conversation from outside the door and called them already. The police broke into the door and took you. You screamed, but they pushed you quickly in the car.

~~~~~~~~~~~~~~~~~~~~~~ One month later ~~~~~~~~~~~~~~~~~~~~~~~~

Thanks to the other teachers and pupils, you had to sit there. White walls, a white bed, a white teddy bear, they even robbed you, you had no phone and it seems like you would die without your Gilbert Shrine. You were but in a psychiatric hospital and actually you wanted to die, but you couldn't, because Mr. Beilschmidt was visiting you every friday and you were so happy about it.
"Hi (Y/N), how are you?", Gilbert said to you and you smiled and answered and also try to not get too hyper: "I guess fine and you" "Good". Then there was silent in the room for a few moments and Gilbert broke it: "I have something for you". He reached into his pockets and took out a necklace with a yellow bird. He got closer to you and put on the necklace around your neck. "Thank you", you said and hugged him. He smiled and answered: "It's alright, but I have to go now. I still have a lot work to do" "Wait", you said and added "I always wanted to tell you....I love you". Gilbert looked at you and answered: "I already know". Then he went outside and left you alone again. You looked down to the necklace and grabbed it and whispered: "Thank you, I love you. I try to get normal again and then maybe we can be together...and no one will gonna stop me"
