3rd person POV

"Muzan!"

A girl with (h/l) (h/c) hair called out to her fiancè, walking towards him while waving up her hand in the air, a bright smile plastered on her face. Muzan turned to face the girl, his lips tugging upward once his eyes landed on his beloved fiancèe.

She finally neared him and embraced him tightly, her face buried into his chest as he wrapped his arms around her warmly and laid his head on top of hers.

"(Y/n), I thought you were visiting next week? Weren't you busy with your family?" He asked, his voice smooth and gentle. (Y/n) shook her head and leaned backwards so she could see his face. "Not anymore! They said they could take care of it and let me go, so that means I'll be bothering you for weeeeeeeeks!"

He chuckled and leaned towards her, pecking her forehead. "I'd be happy that you're here with me then." She then smirked and grabbed his wrist. "Think again! Cause we are heading straight to the waterfall!" "What?"

She laughed and pulled him along with her as she ran, he chuckled at her playfulness and let her drag him to who knows where even when he could stop it since he was much more stronger than her.

They arrived at the waterfall and Muzan stood still, waiting for his fiancèe to talk or something. But what she did next surprised him.

Still holding hands, (Y/n) jumped, pulling him with her unprepared. "What are you trying to do?!" "WATERFALLING!" "(Y/n), I don't want to die!"

He shut his eyes tightly while they fall, an irk mark visible on his face. She laughed it off and they finally reached the body of water underneath the waterfall, making a loud splash.

(Y/n) rose back up the surface of the water and laughed again. "You should've seen the look on your face! You looked so mad!" She didn't hear a reply from him.

"Muzan?" She looked around, and began to panic when she realized he was no where to be seen. "Muzan?!"

She yelped when she felt someone pulling her arm and finally reached the ground. She looked up and there he was. "Muzan! You scared me there! I thought you died!"

He sighed, brushing his wet hair back with his fingers and held out his hand to her. "Come on, we have to go back and change before we catch a cold." "But my legs are tired of running earlier..." she laid flat on the grass and didn't move.

"Oh? Are you sure they're tired? Or are you doing this so I'll carry you?" He smirked while crossing his arms. Her face flushed red and quickly denied it.

He chuckled before kneeling down and lifting her up, his arm behind her back and the other under her legs so she could lean her head on his shoulder.

The way back home was quiet since (Y/n) dozed off but he enjoyed holding her close to him, feeling her warmth and making him feel butterflies in his stomach and as if his heart was gonna burst.

He softly smiled at her sleeping figure in his arms and placed a gentle kiss on her forehead.

"I love you, (Y/n)."

[Time Skip! A few months later]

"(Y/n), are you alright?" Muzan asked, an arm around her waist to assist and prevent her from falling to the ground.

"I-I'm fine, Muzan.. I think I just... need some rest..." (Y/n) muttered and he nodded in understanding. He gently laid her down on a futon and stayed with her, holding onto her hand.

"I'll inform your parent's that you've fallen ill. Is that alright with you?" (Y/n) nodded weakly and closed her eyes. "Just.. stay with me..." with that, she fell asleep.

When she woke up, she was in a different room. It wasn't her fiancè's, it was hers. She was back at home. The door slid open, revealing her parents who stood behind it with a doctor.

"My poor sweet child!" Her mother cried and rushed towards her daughter, hugging her tightly. "Mother, what's wrong?" (Y/n) asked, confused at her mother's actions.

"You have a disease, young lady." The doctor sadly broke the news to her and she tilted her head, a puzzled expression on her face. "But I was fine just a few days ago, that's impossible..."

The doctor shook his head and told her about the disease she had. She was bound to die before she turned 20, but he promised to look for a cure and help her. He then stopped talking, contemplating wether he should tell her or not, but he decided to do it.

"Your fiancè... has the same disease." (Y/n)'s eyes widened and panicked. "D-did I infect him?! Is this contagious?!" She asked, and he shook his head. "This disease may be rare, but it is not contagious. So you needn't to blame yourself." She frowned and tears pricked her eyes. "Please cure him too..." "ofcourse."

[Time Skip]

-In the Kibutsuji Estate-

"What?!" Muzan yelled, frustrated. He sat on his futon, glaring at the doctor who stood infront of him. "I will find a cure for it, so please calm down."

Muzan pulled on his hair, absolute fear overtaking his features. He didn't want to die, and neither does he want his fiancèe to die. Especially with the same disease he's suffering from.

"You better find that cure!"

[Time Skip]

Days turned into weeks, weeks turned into months, and the doctor finally found a cure. He went to his first patient, (Y/n), and used the medicine on her.

"Please wait for it to kick in..." he muttered and (Y/n) nodded, patiently waiting. She didn't feel anything change, she still felt weak then the doctor lifted a spoon infront of her mouth. She parted her lips and the bitter taste of medicine made her cringe. After an hour, she felt completely well, as if she was never sick in the first place.

Tears rolled down her cheek and she looked at the doctor, smiling brightly with gratefulness. "Thank you..." the doctor just gave her a smile and was relieved that she's healed. He went to his next patient, confident that the medicine will work properly and cure them.

Once he entered his estate, the atmosphere wasn't very welcoming. He sat next to his patient and talked to him about the medicine, how it could help him. Muzan sat up, a frustrated look on his face. He was getting impatient, and that made the doctor shiver and immediately gave him the medicine.

When he drank the medicine and felt nothing, he got mad at the doctor. "Nothing is happening!!" Veins became visible on his skin and he killed his doctor before he could even give the second medicine he needed. The blue spider lily. He was surprised by his sudden strength and looked at his hands. His skin were deathly pale but his strength was incredible. He felt... invincible. As if he would never die, and that nothing could kill him.

"The perfect being..."

[Time Skip]

(Y/N) POV

I decided to rest for a week before visiting my fiancè to check how he's doing since we had the same disease, but he was nowhere to be found.

"Muzan?" I walked around his home and it was cold. 'Where is he?' I checked all the rooms, and everycorner of his estate yet he wasn't there. I started to worry.

'Is he alright? Did he get the medicine? Where did he go?' I thought to myself, a frown evident on my face.

'Is... he dead?'
