"Come on, baby, are you going to let me waiting?" He asked you, knocking the door of your bedroom. You had locked yourself in as soon as you heard him breaking into the corridor window. "(Y/N)!" He shouted, clearly getting angry.
You looked around, trying to find something that could get you out of that situation, but there was no way you could think properly.
"(Y/N), don't make me go in there!" He screamed, furiously knocking the door. You could feel your heartbeat growing faster and faster by each second that passed. "Don't make me kill anyone else" Bill said in a lower voice, making your heart stop for some moments.
The flashes of memories invaded your mind and quickly made everything way worse. The images of the dead people, the blood and that dammit bloody knife made you want to puke, though you didn't. You had to find a way out of that situation, you had to end that nightmare. How did one good-looking and interesting boy become such huge issue?
You wanted to kill yourself and just end all of it, but that wouldn't bring the dead back, and you were afraid he would blame someone and simply murder them. He was your problem and you had to deal with him, even if it costed your life or your sanity, it didn't matter. No one else could die.
*************
You were walking down the halls of high school, it was never your favorite place in the world, but you had your ways of surviving. You used to like to simply remain in silence for most of the time, and only talk to your friends, the friends you had since kindergarten...
Then, this new boy showed up. You had never been interested in people at first sight, though that he caught your attention almost immediately.
He had a different name and a different vibe going around him, a closed book ready to be opened and have its secrets revealed.
And just as people always say, curiosity killed the cat. In this case, curiosity drove the cat insane and brutally murdered the cat's best and only friends.
**********
"What did you do?!" You screamed to him, falling in the ground, your voice cracking, your mind exploding, you couldn't feel your senses, you couldn't think. You were paralyzed. You attempted to escape, to run away, but failed miserably.
The bloody and dead bodies of your friends staying right in front of you, consuming your sight and making your head go nuts, you felt as you could vomit, the world around you was spinning round and round, you tried to tell yourself it was just a dream, a bad dream. Though the corpses told you otherwise, that was reality. You remembered all the perfect moments you shared with them, and now everything was gone, they were gone, and you were left alone with the monster, with your monster.
He dropped the knife on the floor, as if it was a mere toy made for kids play around and have fun, the sound of the object that took away the lives of your friends falling into the cold floor made you glance at him. Bill walked into your direction and calmly leaned on. "What do you need them for?" He asked with the psychopathic smile in face, he didn't care for the two lives he had just ended without showing any mercy. "I'm all that you need, baby"
**********
He was threatening to invade your room, and you didn't know how longer the lock would be able to hold him outside.
You stared at the window for some seconds, you could jump and escape. That won't end the nightmare.
You heard a loud knock on the door that brought you back to reality, he was almost breaking in, you had to act and had to do it quickly.
You ran to your wardrobe, opened it without caring at all, you desperately looked for what you needed, for what would end your nightmare, for what would set both of you free. You looked at both sides and tried to breath normally, but reaching air was ending to be a very hard task.
As soon as you found the object you needed so bad, you held it firmly and hid your hands behind your back, only allowing yourself to free one to open the door. Facing the image of Bill, clear anger with the wait burning in his eye, though it didn't stop him from smiling at you.
You tried to control yourself, but couldn't help to shake in fear. If it went wrong, everything would be over. "Finally came to your senses, baby?" He asked "I thought I would have to break in, and I guess we both wouldn't like it, right?"
"R-right" you answered in a whisper.
"Now, will you come with me?" He said reaching his hand to you. You took a deep breathe and hugged him.
"Till hell" you slowly whispered in his ear, before stabbing his back, hoping it would kill him. He pushed you away.
You didn't hesitate one second to jump in him, causing him to fall right into the floor, hitting his hurt back and letting a furious scream out.
Before he could try anything against you, you screamed and stabbed his chest. You had no idea of how many times you did it, but you knew that you kept on doing it even after he was clearly dead.
You couldn't afford the risk of him coming back. This nightmare had to be over. He had to die. He deserved death more than anyone else.
When you finally came to your senses and realized what you were doing, you threw the bloody knife away, with a scared shout. You looked at the dead body you were sat at, the bloody t-shirt and the angry expression still in face.
You looked at your hands. It was hard to find any color that resembled to the human flesh, everything was blood, everything was red and evidences of the recent murder.
You rolled to the other side, lying beside the cold and lifeless body of a killer, the corpse of her ex-boyfriend.
You sat up and closed his eyes with your hands, it was bad enough to know you had just murdered someone, knowing that his eyes were open could only make the feeling slightly worse.
It is over.

I'm back! I don't really read Yandere, so I have no idea if this is something that usually happens in the fanfics, you know. So, if you're obsessed with yandere, tell me if it is something overused.
And hey, you just killed your yandere ex-boyfriend Bill Cipher!
(Next one will be fluffy, I swear)
