Living in Tokyo, all I want to do is laze around.

Hanabi's weak voice sounded like a prayer. As Uesugi Kai listened to that faint voice, he suddenly looked up at her.

"What's wrong?"

The cat stared at her face for a long time, then meowed and rubbed its head against her belly.

"Haha, it itches so much, Kai-kun is still so naughty."

Uesugi Neko made no further moves, but instead curled up in the warmest, softest spot on her stomach.

"Does Kai-kun want to sleep?" Hanabi Hanamaru patted his head and turned to look at the curtains being blown by the breeze.

Outside the window, the rain has stopped.

Hanabi Hanabi looked away and smiled at the orange cat lying on her stomach, saying:

Goodnight, Kai-kun.

"Meow~"

------

Perhaps because of the rain, this morning was fresher and brighter than usual.

In summer, the clear, transparent sunlight appears bright and sparkling.

A gentle breeze rustled the curtains, casting a soft light upon the girl's delicate sleeping face.

Unfortunately, her sleeping posture wasn't very pleasant. Her tank top had slipped down her shoulders, her clothes were disheveled, her navel was exposed, and the thin blanket had been kicked away by her pink little feet.

The cool breeze made her little hands twitch slightly, as if she were trying to grab something.

Perhaps dissatisfied at not being able to touch what she wanted, she frowned and groggily opened her eyes a crack.

The light made her feel a little uncomfortable and her head was a bit fuzzy, but she still heard the door open and saw a figure standing in the doorway.

"Is that Kai-kun?"

"Good morning."

Hanabi Hanabi recognized the voice and mumbled, "Good morning..."

"Sister, sister."

When she came to her senses, she found a very energetic little guy crawling on her.

"It's a rain of flowers."

Hanamaru Hanayu had just woken up and was very excited. When she saw a strap on her older sister's shoulder, she reached out her chubby hand and pulled it down hard.

The little guy was clearly stunned for a moment.

"Drink milk, sister, drink milk."

Hanabi, who had just woken up, was in the most confused state and clearly didn't notice her sister's actions: "Didn't Kai-kun feed Hanabi?"

Kai Uesugi couldn't help but laugh: "She just woke up, and hasn't been fed yet."

"Hua Yu, sister—ah!!"

Kai Uesugi quickly went over and picked up his sister-in-law, who was still reaching out to ask her older sister for milk while in mid-air.

"Huayu, your sister doesn't have any milk to drink."

Hanamaru Hanayu stared at his face for a moment, then laughed heartlessly, burying her head in his chest and rubbing against him.

"Kai-kun, did you see everything just now?" Hanamaru Hanabi's face was flushed, and she was still holding onto the strap of her tank top that had slipped off her shoulder.

"Yes, that's right."

"How...how could this happen..." Hanabi Hanamaru quickly pulled the blanket over herself and huddled inside.

Just as Uesugi Kai was about to speak, a sound came from under the covers.

"Kai-kun, Kai-kun, please go out first."

"Then remember to come out for breakfast."

"Uh-huh!"

Carrying her younger sister who was about to nurse, she walked downstairs, while the two ladies busied themselves with breakfast in the kitchen.

"Grandma, sister, grandma~"

Mrs. Hanamaru was chopping vegetables in the kitchen when she glanced at Kai Uesugi, who had just come down the stairs:

"Where's the firework sauce?"

Kai Uesugi had no choice but to hug Hanamaru Hanayu and face his mother-in-law: "Just now, she climbed on top of my sister, pulled down her pajamas, and bit her."

The two ladies, busy in the kitchen, exchanged a knowing smile.

"Haha, that's really bad."

Kai Uesugi teased Hanamaru Hanayu with his hand: "You can't blame her, she's just hungry."

"Eeya eeya".

"The formula is on the table in the living room," Mrs. Hanamaru said with a smile.

Following Mrs. Hanamaru's instructions, Uesugi Kai spent a few minutes preparing formula for Hanamaru Hanayu.

The little guy was indeed starving; while I was making his milk, he kept reaching out to grab the bottle from my arms.

--------

It was not clear.

Winter is the perfect time to snuggle up in bed and keep warm.

I couldn't bear to get out of bed, nor could I bear to change my blankets into clothes to keep warm.

Even more reluctant to leave the warm little house and go outside to see the snow falling all around.

The fragrance filled her gently rhythmic breaths as Uesugi Kai, enjoying the warmth of the blankets, habitually touched Hanabi Hanabi's little belly beside her.

Her belly was always very soft, smooth and tender, and as you touched it, a warm and comfortable feeling would appear in your palm—and because of this, you would be reluctant to leave it.

But at this moment, Uesugi Kai, with her eyes closed, sensed something strange.

His outstretched hand touched not a soft belly, but a slightly firm, very flat lower abdomen.

Although he was not fully awake and his consciousness was still hazy, he vaguely knew that this feeling was very strange in terms of texture.

He frowned subconsciously, then continued to stroke his stomach, feeling increasingly strange.

Following this feeling, he skipped the belt and slid his hand down.

As he touched her, Uesugi Kai suddenly lost all sleepiness and sat up abruptly in bed.

"you!"

Just as he was about to speak, he realized that the face in front of him seemed somewhat familiar.

Perhaps because he hadn't fully woken up, his eyes were still a little blurry. He blinked several times in a row, and only after his eyes adjusted to the dim light could he be sure that the face in front of him was one he knew all too well.

Kai Uesugi was lying right next to her.

But wait.

He's Kai Uesugi, so... who am I...?

"I...?" He opened his mouth, a sound coming from his throat, a weak voice that was very familiar to him.

What's the sound of Little Fireworks?

Kai Uesugi realized something and stretched out his hands to look at them.

Her wrists were as white as jade, her skin was delicate, and her fingers were slender.

"Fireworks' hand?"

His voice was no longer his usual tone, but rather Hanamaru Hanabi's soft, gentle voice.

He turned his head to look at his shoulder again; it was petite and snow-white, with a pink camisole hanging on it.

My gaze shifted again, landing directly below.

There, beneath the pale pink pajamas, two small mounds rose.

"Am I Hanabi?"

Kai Uesugi patted his cheeks again, and the soft bounce made him understand completely.

I am Hanamaru Hanabi now.

........

Snowflakes fell outside the window. [Hana Maru Hanabi] sat on the bed, her cute face showing a mixture of calm and emotion.

The first time I became a girl, I was naturally curious.

【Hana Maru Hanabi】stretched her hands in front of her, spread her fingers and clenched them together.

Her gaze shifted back and forth between her left and right hands, then she moved her slender, delicate hands upwards, slowly covering the small mound on her chest.

【Hana Maru Hanabi】Carefully bring your hands together.

At this moment, only a thin layer of pink pajamas separated the fingers from the skin, and the softness was simply irresistible.

My hands felt as if they had melted into thick milk.

It was so comfortable it defied description.

【Hana Maru Hanabi】swallowed hard and looked down at the delicate little hands that were constantly kneading the hill.

This feeling was very strange, a strange feeling I had never experienced before.

She could clearly feel the sensations her body was giving her: itchy, a little painful, and a little... comfortable.

"This is... a girl...?"

The kneading hands did not stop; instead, due to a strange feeling in their hearts, they increased the pressure slightly.

【Hana-maru Hanabi】closed her eyes, her throat unconsciously emitting a soft, delicate sound, her cute cheeks began to flush, and her body immediately warmed up.

That's so strange, he quickly stopped what he was doing.

"Is this... how Hanabi usually feels?"
