Yandere! Akito Shinonome x Reader
Warning: Mentions of stalking and yandere tendencies. He doesn't actually kill someone, but wants to :(
~~~
He felt... strange.
Ever since he laid his eyes on you, he always felt this thumping in his heart that yearned for you. He never understood why it happened each time he saw you, but all he knew was that he ever since it happened, his mind only had thoughts of you. These thoughts never changed, causing his grades to suffer and leading him to spend less time with the soccer club just to hang out with you. He knew he was head over heels in love with you, but he was way too shy to confess. So, instead, he'll have to admire you from afar...
...and that meant him stalking your every move.
He sat in his chair in his room, staring at the pictures of you on his wall. Most of them were pictures he took, but some were Toya's from when he begged him to take some of her, and others were obtained through other means. He looked through them, admiring each of them carefully.
There is one picture that is his absolute favorite, one which Toya personally took. It was a picture of you running up to Akito happily and giving him a hug after winning the sports festival. Akito, on the other hand, was a blushing and sweaty mess, both because he ran as fast as he could to impress you and because of the hug. Either way, it was an adorable picture.
He smiled gently at the picture before glancing at the clock. It was 7:36 a.m. He sighed quietly, knowing he had to get ready for school, but at least he would be able to see you today.
He grabbed his backpack full of his school essentials and scurried out the door. Once he got to school, it was about 7:48 a.m., almost time for school to start. He hurried on to his classroom and found you having a conversation with Toya. You were smiling widely, giggling even, which made Akito's heart drop. He couldn't help but feel rage deep within his soul. To resist the urge to punch Toya right in his face, he headed to the bathroom and looked at himself in the mirror. He was sweating profusely, his hands and legs were trembling.
'What is going on?' He thought to himself. 
Suddenly, the memory of seeing you smile at Toya made his chest hurt. He clutched onto his shirt, wanting the pain to go away, but it didn't. He felt like he could faint at any moment. 
Quickly, he ran into the bathroom stall, not wanting anyone to see him in pain. With each passing second, the pain grew at an alarming rate, making him dizzy. 
'Get rid of him,' a voice suddenly called out to him.
"N-No..." Akito whimpered as his back thumped against one of the stall's walls. It was slowly getting harder for him the breathe, but he tried his best to take deep breaths.
'Don't you want them to be yours?' It asked him.
"Y-Yes but," He stammered, but didn't finish his sentence before the voice called out to him again.
'Then find a way to get rid of him or else they will never be yours,' the voice told him.
"But he's my friend!" Akito exclaimed.
'Then your love for her isn't strong enough.'
"W-What?! No! Stop telling me these things!" He yelled. 
Before he can say anything else, his heart suddenly felt like it was going to burst. This pain caused him to drop onto the ground and wince. After dropping onto the ground, there was a sharp pain that occurred in his brain, making him scream out in agony.
