Betrayal, revenge and insanity

Muzan walked through the building, humming a tune while holding his backpack. He searched for his boyfriend, Michikatsu. As he walked he could bear faint whispers of a few people. He simply shrugged and ignored them.

He searched and searched, until he saw Michikatsu. He smiled softly. "Mi-" he froze when he saw Michikatsu kissing a girl. KISSING. HIS boyfriend was kissing someone else. He stopped in his tracks and stared at them. He couldn't believe what he was seeing.

He and Michikatsu had been dating for 5 years now. Why would he do this? He hadn't done anything wrong, did he?

The long haired man slowly walked away, in silence. After a few minutes of silently walking away in shock, he ran to the bathroom. He slammed the door open and panted, sweat and tears falling down his face. He quickly turned the sink on and started to clean his face.

He then turned it off and looked at the mirror. Slowly, he clenched his fists. "Why would he do this to me...? What have I done wrong? Have I done anything to upset him?" He silently sniffled, wiping tears that threatened to fall down his cheeks.

He slowly shook his head and walked out of the school bathroom and walked to class. Luckily he didn't share one with Michikatsu, or he might have lost his mind.

As Muzan sat in maths class, he thought of what to do. He drew a few things in his workbook. Then, he grinned when he thought of something. 'Perfect', he grinned, staring at one specific drawing.

Michikatsu walked to the rooftop, since Muzan texted him to meet him there. He hadn't seen the other and so was excited to see him again. When he opened the rooftop door, he saw Muzan standing near the edge, his long hair flowing in the wind. "Muzan?", Michikatsu asked with a smile, slowly walking up to him and wrapping his arms around the smaller's waist.

Muzan turned his head a bit. "Hi, Michikatsu", he said before looking in front of him again.

Michikatsu frowned. 'Why didn't he say Michi?', he thought. Michikatsu then kissed Muzan's head. "Is something wrong, Muzzy? Did something happen?"

Muzan shook his head. "Can you do something for me?" The albino said with a slight smile.

Michikatsu nodded. "Of course, anything for you", he hummed as Muzan pointed to a spot, one where he wouldn't see the rooftop door.

"Can you go there for a bit? I have a surprise for you", Muzan explained.

Michikatsu blushed and kissed Muzan's cheek. "Alright, I love you",

"... Love you too." Muzan tried not to sound unsure or betrayed, which is hard since he saw HIS boyfriend kiss another girl just 2 hours ago.

Michikatsu walked to the spot where Muzan pointed at just now, turning his head to the other buildings.

Meanwhile Muzan walked to the rooftop door and opened it, but instead of going in, he simply closed it again right after. He then hid behind the cube of cement and went to the other side.

He slowly sighs, before walking to Michikatsu in silence. When he got close, he knocked Michikatsu out. "You said we'd be together forever... Why did you cheat?" Muzan asked the unconscious man, as if he heard him.

Muzan simply scowled. "Don't worry, love, we'll be together forever... Just like you said", the albino smiled and grabbed Michikatsu, before throwing him off of the building.

He then quickly ran towards the security room, luckily he knew a lot about computers. He opened the laptop and quickly entered the password. He then searched for the security camera app and deleted the footage, making sure it's completely gone. Ah, how easy it was, removing all the footage.. It felt so satisfying. How stupid of those school guards to leave this room open for anyone. Oh well.

When he left, he quickly ran downstairs, screaming: "Michikatsu fell off of the rooftop!" And "Someone call an ambulance!" Through the halls as other people followed him, while some other students called an ambulance.

When Muzan arrived at the bottom of the school, he ran towards Michikatsu's dead body. All around his body was blood, from the fall.

Muzan grabbed Michikatsu's body and sobbed into his neck, holding him tightly. Other students surrounded them, whispering among themselves and others panicking about the dead student and his 'lover'.

A few minutes later an ambulance came, followed by the police. The doctors quickly went to Michikatsu and Muzan, frowning in sadness.

"Sir, please get out of the way", the emergency team tried to reason, yet Muzan wouldn't let go. He sobbed, however, je wasn't sad that Michikatsu was dead. He really wasn't. He deserved it. He had it coming. However he was sad that he cheated. He had been nothing but loving, caring, kind, respectful, cheering, supportive and this is what he gets?! Fucking cheated on by the person he gave his whole life for!

After a while, the police got Muzan and Michikatsu('s dead body) separated. Muzan screamed and yelled, kicked and cried and begged the police to let him go. To be next to his lover, to hold him, to be there for him.

They frowned and one hugged the distressed student, trying to calm him down as the ambulance quickly left while another officer got a blanket and wrapped it around the smaller man. Muzan clenched his hands around the blanket, panting, sweating, crying and screaming.

It had been 10 months since the incident and Muzan graduated 5 months ago. Truly he didn't care about Michikatsu's death, he thought the other deserved it. Of course he did make sure to show oh how sad he was, how broken he was that his 'lover' was dead.

He laughed lightly as he thought about that time. Truly all of them are fools. He'd also found the girl Michikatsu cheated on him with, and let's just say her funeral will be in a few months.

He walked to the graveyard, holding a shovel, bucket, towels and a knife. When he entered the graveyard, he immediately searched for Michikatsu's grave.

After 10 minutes of searching, he found it and started to dig. He made sure that nothing was damaged, and of course he covered the security cameras so he won't be caught.

After a while, he finally hit Michikatsu's casket and so he lifted it out of the hole. "Fuck... So heavy!" Muzan hissed, until he finally got it out. He then opened it, smiling when he saw Michikatsu.

"Oh love... Don't worry, we'll be together again soon", Muzan stated, kissing Michikatsu's forehead. He then grabbed the knife and started to stab Michikatsu's head, gently as to not scrape his brain. When he got the brain, he gently placed it into the bucket. Then, he did the same for Michikatsu's lungs, heart and stomach.

He stared at Michikatsu's eyes. "Mm... I wonder..." He then opened Michikatsu's eyelids and smiled like a maniac before carefully scraping them out too. He then grabbed the towels and cleaned everything up. Muzan closed the casket and put it back in the hole. He grabbed the shovel and put the dirt over it again.

He then went home.

It had been 7 years after Michikatsu's death, and Muzan had made a life-sized clone of him, with the same personality, looks and everything! He had to admit he was very proud. Truly his skills in cloning had become amazing, even if he says so himself. Of course he made sure the clone didn't remember things like arguments, but Muzan did make the clone remember that Michikatsu cheated, so he'd be very obedient.

Right now, Muzan was cooking some food. "Honey, how was work?" Muzan asked with a smile to his 'lover', kissing him on the cheek. He referred to 'Michikatsu' pretending to be someone else and doing a very good paying job. How you may ask? Murder, of course.

"It was alright, how have you been, my angel?", the clone asked with a smile and held Muzan tightly against him, gently kissing his head.

"I'm alright. Sit down, food's almost ready." Muzan simply smiled and went back to cooking. He then put both of their meals on their plates and they began to eat.

"My angel?", 'Michikatsu' asked with a soft frown on his face.

"Mh?", Muzan hummed as he ate.

"I just want to say how much I love and appreciate you. And I apologize again for my actions. I have no idea what was going through my mind and I hurt you. I hurt my angel and I will do everything in my power to show you how much I love and appreciate you."

Muzan blushed and smiled. He got up from his seat and kissed the clones cheek. "Aww my love... I do have a few things you can do to make me forgive you."

"I will do anything."

"For starters... I want a few cats, blue spider lilies and of course a pool", Muzan grinned, fully taking advantage of this. They were rich anyway, who cares?

The clone nodded. "I shall do so, I will also make sure that we shall live as comfortable as possible."

Muzan giggled and kissed 'Michikatsu's' cheek. "Yes... But remember, no one can every know how you look, or your real name, remember?"

"Yes, my love. The world is dangerous and you just want to protect me from harm."

"Yes... I love you, Michi", he kissed the clone's cheek again.

The clone wrapped his hands around Muzan's waist and kissed his neck.

The action made Muzan giggle and lift the clone's head up. "We'll be together... Forever."
