Demon Slayer: I am a Demon.

Sleepiness crept in without me even realizing it.

Nezuko then slightly adjusted her position in Su Mu's arms, gently closed her eyes, and her breathing immediately became steady.

…………

Su Mu gently patted Nezuko's soft back, feeling the soft and tender Nezuko sleeping in his arms.

He had felt and experienced the gentleness and vitality of the woman in his arms... It was wonderful, full of pleasure and excitement.

But afterwards, there was a very unreal feeling.

Looking down at the girl's delicate and lovely face with its blush, and at her long and beautiful eyelashes, he suddenly realized that he had completely possessed this girl.

In the world of Demon Slayer, she is arguably the most popular female character. Who would have thought that I would have her all to myself now?

It feels like a dream.

Looking down at Nezuko, who was sleeping soundly in his arms, the girl's long, thick eyelashes cast a small fan-shaped shadow under her eyes. A slight smile played on her lips in her sleep, as if she were having a sweet dream.

He recalled the girl's initial trembling last night; her tearful eyes clearly showed fear, yet she still bit her lip and didn't take a single step back.

"From now on... I'll leave this to you."

It's as if they want to completely entrust everything to themselves.

In fact, he did feel it and he did receive it.

It refers to unconsciously stroking Nezuko's hair.

Her long, black hair was spread out smoothly on the pillow, setting off her fair and rosy face, like a painting.

He suddenly felt a little dazed.

How long have I been in this world? From initial confusion and wariness, to relying on Kanao for survival, finding the Blue Spider Lily, and becoming a perfect demon...

But in fact, before that, he could never fully trust anyone except Kanao.

But now, it seems I can trust someone again.

Because this person seems to want to completely entrust everything to you, and you don't seem too worried that the other person will betray you.

A clear bird song drifted in from outside the window, followed by a second and a third, like a morning chorus. The bamboo grove in the courtyard rustled in the wind, and occasionally, early-rising servants could be heard conversing softly in the distance, their voices indistinct and distant.

Su Mu lay quietly, showing no intention of getting up.

In the past, he might have already risen up, or guided the swordsmen of Mount Sagiri in their training, or done something else, but now, he is greedy for the gentleness here and doesn't want to move at all.

The warmth of the girl in his arms seeped through his skin, a gentle warmth that burned from his chest to every part of his body.

This must be what they call a "gentle haven".

…………

When Nezuko woke up again, the sun was already high in the sky.

She opened her eyes groggily, her first thought being – how warm it is.

Then she realized that she was being held in a strong embrace. The man's body temperature was much higher than hers, like a natural heater, enveloping her in warmth.

And her hand, without her noticing, climbed onto his chest, beneath which lay a steady, powerful heartbeat.

Boom, boom, boom...

Each beat was steady, like the beating of a drum.

Nezuko's face turned red again.

She secretly glanced up and found Su Mu looking down at her. His eyes, which usually held a certain aloofness, were now filled with a faint smile, making him incredibly gentle.

"Awake?" he asked.

"Hmm..." Nezuko responded, her voice still soft and sweet from just waking up, "Hasn't Master gotten up yet?"

"Wait until you wake up."

Those three short words melted Nezuko's heart instantly.

She bit her lower lip, mustered her courage, and whispered, "Sir, you don't need to wait for me... If you have something to do, you can get up first..."

"Nothing much to do today," Su Mu said, twirling a strand of her hair between his fingers. "I just wanted to hold you a little longer."

Nezuko felt like she was about to faint.

What's wrong with you today, sir? Every word you say sounds like it's been sweetened with honey, so sweet it's making me dizzy.

The girl buried her face in his chest, her voice muffled: "Sir... you're acting so strange today."

What's strange about it?

"It's just... it's different from usual."

Su Mu chuckled softly, the vibrations from his chest sending a tingling sensation through Nezuko's eardrums.

"What's different?"

Nezuko thought for a long time but couldn't figure out how to describe it. In the end, she could only manage to say, "Sir, you wouldn't have said something like that before."

“The past is the past,” Su Mu tightened his arms. “The present is the present.”

Nezuko understood, yet it seemed she didn't. She just felt a sweet warmth in her heart, like she had drunk a large bowl of red bean porridge, the sweetness spreading from her throat all the way to her stomach.

……

Another half hour passed before the two finally got up.

When Nezuko was getting dressed, she noticed that her pale cherry blossom-colored yukata was wrinkled beyond recognition, and there was even a tear at the neckline, revealing a small section of her fair collarbone.

The girl's face flushed red. She hurriedly wrapped her clothes tightly around herself and then pulled out a new hairband from somewhere to tie her disheveled long hair back up.

Su Mu was already dressed and sitting by the window, reviewing the intelligence that had been delivered that morning.

Nezuko walked over, knelt down beside him, hesitated for a moment, and then poured him a cup of tea.

"Sir, are you... going out today?"

"I'm not going out." Su Mu didn't even look up. "I'll stay with you today."

Nezuko's heart skipped a beat, then started pounding again.

To...to stay with her?

Her husband had never said that before. Her husband had never treated her so gently.

And today...

Nezuko hung her head, twisting the hem of her clothes with her fingers, but she couldn't suppress the smile on her face.

"What are you thinking about?" Su Mu's voice suddenly approached.

Nezuko was startled and looked up to find that Su Mu had put down the intelligence in his hand at some point and was looking at her with a look of inquiry and a mischievous smile in his eyes.

"N-nothing!" Nezuko hurriedly denied.

"Really?" Su Mu reached out and pinched her burning earlobe. "Your ears are so red, and you still say it's nothing."

Nezuko felt like she was on fire and instinctively tried to dodge, but Su Mu scooped her up and pulled her into his arms.

"Sir!" the girl exclaimed, her voice filled with embarrassment and annoyance, but she dared not speak loudly for fear of disturbing the people outside.

"Don't move." Su Mu's voice was low and languid. "Let me hold you for a while."

Nezuko then stopped moving and nestled obediently in his arms, like a docile kitten.

The sunlight streamed in through the window, falling warmly on the two of them.

Nezuko closed her eyes, listening to her husband's heartbeat, and suddenly thought how wonderful it would be if these days could continue forever.

…………

Su Mu and Nezuko hardly left the house all day. Their lunch was brought over by Kamado Aoi. Looking at her rosy-cheeked daughter and the youthful charm in her eyes, Kamado Aoi probably understood something.

Actually, at this moment, Kamado Aoi was a little worried.

As a very traditional woman, I always felt that everything should happen at the moment of marriage. I wondered if it was wrong for Nezuko to give everything away so quickly. What should Nezuko do if the man is irresponsible?

However, judging from your appearance, you don't seem to be that kind of person.

Moreover, seeing his increasingly considerate attitude towards his daughter, I feel... perhaps I am being too old-fashioned.

…………

When Tanjiro arrived, he saw Nezuko kneeling in the room, head bowed, calmly brewing tea.

Nezuko has actually been learning the art of tea ceremony, and now, the young girl can brew very good tea.

When his sister brewed a cup of tea and handed it to him, Tanjiro felt that his sister seemed a little different, but he couldn't quite put his finger on what was different. He could smell the scents of his sister and his teacher, and felt that their scents were intertwined very deeply.

I vaguely sensed something.

A sense of loss welled up in Tanjiro's heart.

Tanjiro's identity is no longer limited to the eldest son of the Kamado family. With his joining the Demon Slayer Corps and carrying out several demon-hunting missions, he has quickly risen from the lowest-ranking Rank 1 swordsman to the current Rank 1 swordsman.

Perhaps due to Tanjiro's naturally gentle personality and personal charm, he is very popular in the Demon Slayer Corps and has many close partners who are willing to entrust their backs to each other.

Tanjiro came here because he wanted to carry out a demon-slaying mission.

After carefully reviewing the information about the demons Tanjiro wanted to hunt, Su Mu concluded that they were just ordinary demons and probably not from the Twelve Demon Moons, so he agreed to Tanjiro's request.

Tanjiro should have been happy, but looking at his sister Nezuko's condition, he suddenly felt a sense of emptiness.

Su Mu could understand Tanjiro's feelings. After all, Tanjiro and Nezuko had a deep bond, but no matter what, siblings are still siblings.

Tanjiro, as the older brother, would eventually face this day.

"Bon Voyage."

Su Mu patted Tanjiro on the shoulder.

"Brother, please be careful."

Nezuko's eyes also showed worry.

…………

Are you very worried?

After Tanjiro left, Su Mu came to Nezuko and gently hugged the girl in his arms.
