Giyuu woke in the middle of the night to the feeling of being watched. This was common for him as he has always felt anxious and stalked without his medication. But this felt diffrent...this felt real. He simply shrugged it off and rolled over in bed and snuggled back into the comfort and fell back asleep. Just as he closed his eyes, a figure climbed down from his windowsill. The next morning when he woke up, he got dressed, cleaned up and went to school. He was in his 3rd year of college and had a best friend named Koch Shinobu. There was also a boy who he thought was pretty nice to him. This boy was named Sabito. Sabito would always wait for Giyuu and help him with homework and generally be a good friend. That morning Shinobu was flirting with Tomioka and he was just laughing it off and blushing tremendously even though he liked men.

"My my Tomioka-San! Your looking very nice today!"

"Um...thanks?"

"You really are hopeless you know that?"
Giyuu just rolled his eyes and walked to class with her. Sabito turned his head from put of the shadows and silently followed them ro class. The two of them turned the corner and sat down on a bench and pulled our their binders. Sabito sat down a few benches down. Giyuu and Shinobu were finishing there calculus homework together when Shinobu whispered something in his ear and kissed him on the cheek. Giyuus whole face turned red and he put his head in his hands. On the other side of the spectrum, Sabito's face was dark and shadowed as he slowly got up and left. The day went by with Giyuu and Shinobu going around to their classes and learning and Sabito following the two, unknown to them. Shinobu kissed Giyuu a few more times thay day and each time Sabito became more and more jealous. He had the same classes as Giyuu making it perfect to spy on them. As the day came to a close, it was studying time for about 2 hours before everyone was dismissed. Giyuu and Shinobu were sitting on the rooftop and finishing any additional homework they were given that day. Sabito was as well. It was the first time he was with them that they knew about. The three of them just talked and finished homework until it was time to go. It was a good time but Giyuu's foster mom needed him home. He said his goodbyes to Sabito and Shinobu and walked down the stairs. Sabito got up and slowly walked over to Shinobu.

"Stay off of him..."

"What?"

"Stay the fuck off of him you little shit."

"Sabito-san...I don't understand...."

"Then this will make you understand."
Sabito came a little bit closer to Shinobu and shoved her off the roof. She stumbled back and grabbed on to the guard rail and tried to pull herself back up but Sabito used his binder to crush her fingers resulting in her falling from 12 storys up on her neck. Sabito brushed off his hands and walked away. As he walked down the stairs he saw Giyuu catching up with his friend Tanjiro. Tanjiro was a freshman but he was still very close to Tomioka. As he listened in on their conversation, he found out that Giyuu was invited Tanjiro to come over to get help with his business homework. He decided he would get rid of him after he left Giyuu's house so he started to follow them, hiding in the shadows and alleys as he walked behind them. It was a long walk. About 45 minutes. It was even longer if your trying to stay hidden the entire time. Once they got to Tomioka's house, he his in the alley next to his neighbors house. He and Tanjiro worked for about 3 hours or so and in that time, Sabito figured out exactly how to kill Tanjiro. After Tanjiro and Giyuu finished the work Giyuu offered to walk him home. This put a flaw in Sabito's plan so he followed them, trying to hide in the shadows and be absolutely silent. They got there and Tanjiro said his goodbyes to his friend and walked the few feet to his door alone. Big mistake. As he was about to reach the front door, Sabito jumped out of the bushes with a pair of safety scissors and tackled him to the ground. Giyuu heard his yell and quickly turned around to help and he saw Sabito on top of him trying to stab him in the neck with the scissors. Giyuu ran to intervien, but it was too late. Sabito had stabbed Tanjiro in the neck 4 times before he died. Giyuu looked up from Tanjiro's dead body and saw Sabito. He was shocked.

"S-sabito?"

"Yeaaaaa! Do you love me knoww?"

"What...?"

"Do you love me Tomioka-San?!"

"HOW COULD I EVEN SEE YOU AS A FRIEND?! YOU JUST KILLED TANJIRO!"

"Oh...I thought getting those two out of the way would help you love me more...guess I was wrong!"
The cheerfulness jn his voice made Giyuu sick. But then something Sabito said registered in his mind.

"Wait...you said 'those two'..."

"Yea I did!"

"Do...do...do you mean....Kocho?"

"Is that her name? I couldn't remember...is she the butterfly girl in your calculus class?"

"WHAT DID YOU DO TO HER?!"
Giyuu shouted at Sabito with tears pouring down his face. How could he. They were best friends. Why.

"Relax Tomioka-San! She's gone now! It's just you and me!"

"I WOULD RATHER DIE!"
With that, he started tonsprint away from Sabito. Giyuu got out his phone and started to dial the police when he felt a handngrab his ankle and pull him down.

"SAY YOU WANT ME. SAY YOU LOVE ME. SAY I CAN HAVE YOU!"

"NO! YOU CANT YOU BACKSTABBING FUCKWAD!"

"If I can't have you...no one will."
Sabito lunged at Giyuu and stabbed him in the throat the same way he did to Tanjiro. It took 2 stabs before Giyuu started having ringing in his ears and his vision blurred.

"I'm sorry Tanjiro, Shinobu....I'm sorry you loved me..."
With those final thoughts he had before every thing went black and he heard

"Sweet dreams Tomioka-San!"
Tomioka Giyuu was now dead approximately 3 blocks away from Tanjiro buy stabbing to the throat. Sabito was immediately taken into police custody and sent to a mental assluym. Though he bad a slow recovery, someday he would just stare out the window thinking of his best friends now dead attractive face.
