A story of a past love

A/N: Kokushibou will be referred to as Miyashita Takahiro, and Muzan will be referred as Sheya after the flashback.

Muzan and Kokushibou walked through the forest. It was quiet, which they both liked. "Darling", Kokushibou said after a bit, which made Muzan open an eye and hum. "Yes?"

"You told me that you knew me in a past life. Could you... tell me about it?" Kokushibou asked, slowly wrapping an arm around Muzan's waist.

Muzan smiled softly. "Curious? That's unlike you, my love", he teased, wrapping an arm around Kokushibou's neck.

"That is not bad, is it?" Kokushibou smiled back, putting his hands on Muzan's hips.

The older hummed, slowly turning around again. "I suppose I could... But, we should go home, don't you think?"

The six-eyed demon nodded. "I suppose that would be the best."

Muzan snapped his finger, and in a second they were in their shared bedroom. Muzan had changed into a sleeping robe, while Kokushibou was still in his hakama pants and top. Muzan sat on the bed and pat the spot next to him.

Kokushibou had changed into a white sleeping yukata and sat next to Muzan. "Well, I first saw your past-self in the Heian court..."

⋇⊶⊰❣⊱⊷⋇

Kibutsuji Muzan, or rather, Kibutsuji Sheya, walked through the halls of the Heian court, he had been cured from the disease he had been born with. However, a few things had changed. His first soft lavender eyes, filled with fear, dread and sorrow were now a bright red colour. His pupils slightly changed, his skin had become paler, his nails had grown.

Yet, people found him just as beautiful.

Pitiful.

Sheya had been invited to a 'party' from the court, as he was successfully cured. "This is a waste of time, Kagaya", Sheya hissed at his older brother.

"I know, I know. Don't worry, we'll be gone before you know it", the older reassured, a smile plastered on his face.

"Perhaps you might even... find a lover", he smirked at the younger one.

"Don't be so foolish, love is nothing but a waste of time. Plus, they're nothing but old men, I'd rather kill myself than be married to any of them." Sheya said with a harsh tone, a vein on his head.

Kagaya couldn't help but laugh lightly. "Okay okay, but hey, I did hear that a youngster was in training", he smiled. "He's the heir of the Miyashita clan."

As they walked, Kagaya kept talking about all the people in the court, as if his younger brother was actually listening.

They arrived at the court. "It iss quite fancy, one of the only things humans are good in", the smaller demon said, looking around the court as they walked. The men of the court sat there, smiling.

Sheya gave them a quick smile before looking around again. He'd never been here, he was curious about all the things that happened here.

A handsome man sat next to the Miyashita clan leader, which Sheya assumed to be his son. Kagaya walked to the other men, while Sheya went to the corner.

"Hello, you are the Kibutsuji heir, am I correct?" a gentle voice said. It was Takahiro.

Sheya sighed softly before turning his head to the other. "Yes, what do you need?"

"Well, sir, since we're both heirs of our clans, I wish to be friends with you, Kibutsuji-san", he smiled and sat down. Takahiro was perhaps 23 years old, quite handsome to some degree and polite. "It truly is an honour to meet you, Kibutsuji-san."

The smaller man hummed. "I suppose so. And truly, why is it an honour to meet me?" Perhaps it looked like Sheya was fishing for compliments, and so what if he did? He deserved the praise for keeping up with that disease for 19 sickening years instead of giving up and letting that damned illness take his life.

"Well, Kibutsuji-san, I mean, you did live through... that, didn't you? What is it, 19 years and still standing? How admirable", Takahiro sighed and smiled, his voice was soft, and his expression showed it.

Sheya hummed. "Why thank you."

Takahiro smiled, putting a hand over Sheya's. He was genuinely interested in Sheya, his beauty was comparable to the sun goddess herself. "Truly, you are very beautiful, Sheya."

A light blush spread on Sheya's face, followed by him turning his head away. "Mh, I've been told so before." He smirked. "Do you not have any... How do I say this, original compliments, Takahiro-san? I'm curious." He leaned closer, staring through his dark eyelashes.

Takahiro laughed at his comment. He noticed the blush on his face, and immediately got an idea. Takahiro's lips then slightly curved, he had a mischievous spark in his eyes.

"I do, I just thought you would appreciate compliments that were given to you in the past."  He suddenly leaned closer to Sheya, his breath was gentle when it touched his lips. He whispered to him: "Just to add a little twist to this, Kibutsuji." He chuckled lightly.

Slowly, Sheya stared at him with wide eyes. He slowly pulled away, his face turning light red. "You... You lousy pervert..." He scowled, grabbing a fan and waving it in his face. "You have no shame, do you? Or are you a cut-sleeve¹ ?"

Takahiro laughed out loud, his eyes shimmered with amusement. "Why would you say I have no shame, Kibutsuji-san? You should see the look on your face. This was certainly worth it", he chuckled.

"It's not too bad though, seeing you blush brings so much satisfaction. How fun. What if I am a cut-sleeve?"  He smirked playfully.

Sheya stared at Takahiro with a glare. "Utterly shameless!" he scoffed, turning his head away. He waved the fan in front of his face, sighing.

"Do not even think about it", Sheya bonked the other with his fan. "You sound like an hormonal child." Sheya hummed, putting a hand in his lap.

He laughed when Sheya bonked him with the fan. It certainly felt like a childish moment between them both. "I wonder... what would it be like to make you... not so shy?" Takahiro hummed, leaning closer to Sheya and looking down at him. What if I put a little more pressure on him?

Sheya simply scowled. "I'd prefer to stay a virgin², because unlike you hormonal beings I have preferences. The thought of having... that sounds like something I'd do with a trusted partner, not a one night stand. Or do you believe I'm a common whore?"

Takahiro laughed when Sheya scowled at him. That made it even more fun. "Oh, how cute", he smirked. "You misunderstood me, I wasn't trying to make a move on you. That was all an act, to make you blush more. Your reaction is so amusing, I could just imagine you being in an intimate moment with your precious partner," he chuckled. "I bet I can make you blush more."

Sheya rolled his eyes. "I would rather perish. How about we talk about relevant things instead of... whatever this is."

Takahiro was not giving up on this one. "Why so serious? Your face is still red from me making you blush earlier. This is what is fun", he laughed again. "You are a very amusing boy. Maybe if you open up to me, you could tell me about your beloved partner."

"You really are an hormonal child. And I do not have a partner, I do not need one. Love is nothing but a waste of time."

Takahiro laughed again as Sheya said that. "You're certainly a hard one", he said as he ran a hand through his hair, thinking about something. "Do you plan on not having a partner for the rest of your life? Or do you plan on eventually finding your "trusted partner"" he smirked again.

Sheya couldn't help but lean into the touch of his hair. He slowly closed his eyes and leaned into Takahiro. He nuzzled into Takahiro's chest, slowly purring.

Takahiro smirked and caressed the back of his head. "Aww. How cute." He suddenly smirked and gently grabbed his chin, pulling him closer. "What made you suddenly come closer to an "hormonal child?" You were scowling just a bit ago. Your mood changes are very drastic, Kibutsuji."

"So what if they are? Do you wish to be close to me or not?" He hummed, humming softly as Takahiro's hand ran through his hair.

Takahiro was enjoying this. "You're a fun one, Kibutsuji", he said as he gently placed a hand on Sheya's hip. He then smirked at his comment. "Ah, I do wish to see you as close as possible. Would you like that?"

"Perhaps I do", Sheya stated before closing his eyes and falling asleep.

Takahiro smiled and gently picked the sleeping man up. "Could you show me his room, Kagaya-san?"

"Of course, Takahiro-san."

It had been a few months since Sheya and Takahiro had known each other. Takahiro would often visit Sheya, giving him all sorts of things, hairpins, kimonos, flowers, you name it! Sheya had to admit he quite liked being so spoiled.

Takahiro had grown quite attached to Sheya, in a way, he thought of that man as his partner. He had developed a small crush on him from his time of visiting the Kibutsuji.

The little gifts he had brought were enough to see him smile. He would sometimes even stay over and give his time to the Kibutsuji, he loved giving him attention.

Sheya was laying in Takahiro's arms, gripping his kimono top. "Takahiro..." He mumbled softly, blushing.

Takahiro turned his head and looked down to Sheya. His face was filled with joy whenever he saw the pale man. "Hmm? What is it, Sheya?", he softly replied. Takahiro caressed his cheek as he looked at him, his hands were warm and gentle.

"I want to have sex."

It was a bold statement, Sheya knew so. "Please. I... I'm ready."

Takahiro stared at the younger one. "Oh?" He smirked softly. "Alright, how do you want it?"

Sheya blushed softly. "I... I don't know." He looked away in embarrassment.

"We can take it slow, my dear. Let me show you what I have in mind." He gently guided Sheya onto the bed, propping up some pillows for support. He leaned over Sheya, taking his white haori off. "Love, if you can't take it anymore or you want me to stop, say lotus, okay?" Takahiro smiled, gently kissing Sheya's cheek.

"Lotus... Alright", Sheya nodded as he started to take his yukata off. Sheya sighed and struggled, shaking slightly.

Takahiro's warm breath brushed against Sheya's neck as he spoke. "There, there. It's okay to be nervous, my love. Just relax and enjoy." He assured the smaller one, gently caressing Sheya's thigh.

Sheya gave a soft nod, slowly laying down again. He closed his eyes as Takahiro's lips traced over his exposed shoulders.

His lips brushed against Sheya's skin, tracing over the delicate bones of his shoulders. "Do you trust me?" He asked softly, looking into Sheya's eyes.

"Takahiro-san, do you believe me to be a common whore who sells their bodies? I would not do this if I did not trust you", Sheya stated calmly. Sheya slowly began taking Takahiro's top off, blushing

"You must train a lot..." He said as he slowly traced his hands over Takahiro's bare chest.

"No, I don't think you're a common whore. You're far too precious for that." Takahiro smiled softly, his hands coming up to rest on Sheya's hips. "And yes, I train quite a bit", he said as he began spreading Sheya's legs.

Sheya blushed softly. "Mh... Quite the gentleman, aren't you?" Sheya teased, a slight smirk on his face.

Takahiro chuckled softly, his hands moving to gently massage Sheya's inner thighs. "I like to think so, my love." He leaned in, pressing a gentle kiss against Sheya's neck.

Before Muzan could continue, Kokushibou had pinned Muzan down. Kokushibou smiled softly. "Shall we, instead of telling it, recreate it?"

Muzan smiled back. "Go ahead."

¹ Cut-sleeve 断袖 (duàn xìu) is a euphemism that refers to male homosexual individuals and male same-sex love in Chinese culture. The term dates back to the late Han Dynasty, around 10 BC. Since the Heian Court was influenced by the Chinese, it could be that they also used cut-sleeve as a euphemism.

² In the Heian Period, it would be frowned upon if a girl was a virgin for a long time. Because of Muzan's illness, he became weak, and some considered him more feminine than masculine.
