My girlfriend is actually myself.

Without immediately turning off the lights, Shiraishi Saku scrutinized the girl's body beside him.

Long golden hair, azure eyes, a languid expression, a body pressed close together, and his arm cushioning her.

Even from a god-like perspective, without interfering with the girl's thoughts, Yukimiya Natsune was no different, just like all the previous nights.

Some habits, such as the way he tucks in the blankets, haven't changed; they're still his habits.

It would be strange if there were any changes. People are made up of the past. Yukimiya Natsune has been living like this for the past half month, so of course it will be the same now.

Thinking about it this way, if Yukimiya Natsune really exists, then a girl who inherits his way of thinking might be more in line with the concept of a daughter.

Thinking about it this way, Asakura Airi, who said those things during the day, became even more perverted. Shiraishi Saku recalled what happened at lunch. Although his original purpose in creating that 3D model was to use it as a spellcasting material, talking to himself was still too stimulating.

The scenario of "cutting yourself in half" might seem normal, as many people do it at night. However, from another perspective, the act of cutting yourself in half is a true test of one's resilience.

Furthermore, because one clearly and consistently recognizes that it is oneself, a necessary element is missing—sexual fantasy. Just like simply looking at one's own hands without indulging in fantasies, one will not feel anything.

In contrast to the real body, the 3D model of Yukimiya Natsune in the computer can be captivating, as can photos and videos of a young girl's body, because images and photos are isolated from reality and do not trigger the correction of self-awareness, thus allowing for a space for fantasy.

Unlike the legendary beautiful boy who falls in love with his own reflection, the girl's body is not Shiraishi Saku's reflection, but rather his own. Reflections cannot think, and while the beautiful boy can project fantasies onto his reflection, the reflection will not refute him. However, the girl's body can think along with Shiraishi Saku, making it difficult to project fantasies. The girl's self-awareness will correct any fantasies.

At least from the first-person and third-person perspectives, the girl's body is an extension of Shiraishi Saku's limbs.

As for the God's-eye view...

Shiraishi Saku looked at the girl in front of him, his gaze tracing her fair cheeks before settling on her cherry-red lips.

Yukimiya Natsune looked at him, blinked her blue eyes, and raised her slender white finger, tapping it on her chin.

"Want to try some, papa?"

Even from God's perspective, the girl's body can still know the boy's thoughts. She has already read the "daughter theory" and reacted accordingly.

However, is this a reaction of the girl's body itself, or the result of the independent operation of the thought model that Shiraishi Saku left in the girl's mind?

Shiraishi Saku pinched the girl's cheek with his free hand: "Don't act like a child!"

The word 'papa' can be understood literally as 'baba,' but only children use that word.

"Would you like to try some, Father?" Yukimiya Natsune corrected her address, her voice changing from childish to elegant.

"O-fu-sama" is a line often spoken by young ladies in movies and TV dramas.

Shiraishi Saku did not answer, and raised his hand to turn off the light.

……

Outside the tower window, the dazzling lights of the Tokyo Skytree went out into the darkness; it was past midnight.

In the dim light of the living room, Airi Asakura hugged her knees, huddled in a corner of the sofa, her gaze vacant.

She's been waiting since the afternoon, but the door hasn't opened at all; Yukimiya-chan still hasn't come home.

Did you spend the night there?

They must have spent the night there!

They didn't even kiss during the day, but they spent the night together!

I told you to act quickly, but not this quickly!

Isn't it usually done step by step? Won't it break if you do it all at once?

Airi Asakura hugged her head, putting herself in Yukimiya's shoes, imagining herself taking nine doses of magic potion and performing nine rituals in one day, and how she and Shiraishi went from being lovers to lovers.

No, her body can't take it, she'll go crazy!

Is this the difference between her and Yukimiya-chan?

Are truly mature young women really this terrifying?

Airi Asakura trembled.

……

"get up!"

Sakura Nene jumped onto the bed, stepped on her brother, and shook him back and forth.

She recently discovered a pattern: whenever she wakes her brother, her older sister Yukimiya will immediately wake up as well.

Sure enough, under her stomping, Yukimiya and her brother opened their eyes and sat up at the same time.

"Go wash up!" The girl jumped out of bed and left the room.

Bai Shishuo leaned against the headboard and rested for a while. For some reason, his back was a little sore, even though he hadn't done anything last night.

He reached out and rubbed it, only to find it useless. He then realized that the feeling did not come from a boy's body, but from a girl's body.

But the girl didn't do anything last night.

Shiraishi Saku fell into deep thought.

"..."

"...?!"

Turning his head, he met the girl's gaze, and then both eyes looked together at the girl's waist.

Shiraishi Saku lifted the covers, and Yukimiya Natsune lifted her nightgown. Their eyes met, and they both sighed.

This was expected, since the girl's body was almost a month old, but it was unexpected that it would happen at this time.

Shiraishi Saku was prepared, and after cleaning, he considerately dressed the girl in new gear.

Fortunately, I only have some lower back pain and fatigue, but no other symptoms.

They didn't take it to heart and continued as before, getting dressed, washing up, and going downstairs.

Breakfast was ready, but the girl had a poor appetite and had no desire for the cold milk.

Shiraishi Saku ate the breakfast she hadn't finished.

Sakura Nene stared at Yukimiya Natsume for a while, narrowed her eyes, nodded with satisfaction, and got up to take a small storage bag out of her schoolbag.

"Here you go." The girl handed the small bag to Yukimiya Natsune. "Inside are sanitary napkins, wet wipes, painkillers, heat packs, and a change of clothes... Ah!"

She put away the storage bag, changed the underwear inside, and handed it to Yukimiya Natsune again: "I have one more, this one is for Yukimiya-nee!"

The girl was somewhat smug, because she had been observant and discovered the truth, and also because her spare menstrual kit had finally come in handy.

"You're quite observant." Bai Shishuo reached out and rubbed his sister's head, confirming her guess.

"Absolutely!" The girl raised her head even higher. "I watch every day to see when my brother's baby will be born."

"...?"

Shiraishi Saku thought the sound of that little head tapping must be very pleasant.

"Brother and Sister Yukimiya have a good sense of safety," Sakura Nene praised. "Please keep it up. One child like me is enough for this family; please don't have any more for now! I don't like children!"

The girl crossed her arms and solemnly stated her position.

Shiraishi Saku tugged at her pigtails: "Don't worry, I don't want to get pregnant either."

"What are you saying, brother? If anyone should be pregnant, it should be Sister Xuegong," the girl corrected her brother.

Shiraishi Shuo turned her around so she could cool off somewhere else: "You don't need to worry about that."
