Tosaka Fuyuka stopped feeding Kazuma. After eating half the noodles, she placed the cup in his hands. Hugging her knees, she sat silently, only glancing at him as he slurped from chopsticks still wet with her saliva.
Thoughts like "indirect kiss" kept spinning in her mind.
I even ate his saliva too!
Her face must be bright red. She felt shy and slightly frustrated. Why hadn't he reacted? Even sharing noodles—or just a pair of chopsticks—he should have shown some kind of response.
But Kazuma treated it like nothing out of the ordinary.
That calmness made Tosaka Fuyuka, always anxious and uncertain, feel even more uneasy.
Why are you so calm?
"Wait… does this mean my relationship with him is unusual?" she thought. "I've never really considered it before. If we were dating, then something like this wouldn't be strange at all."
Her anxiety deepened.
Am I his girlfriend?
Back in the wallpaper room, Kazuma handed her a blanket. But Fuyuka tossed and turned, unable to fall asleep. Sleeping near a boy didn't feel wrong, not at all. She looked at him lying nearby, her eyes curious as they studied his back.
"Kazuma, are you asleep?"
"I'm awake."
"I can't sleep. Talk to me," Fuyuka said, sitting up, her long hair cascading over her shoulders. "There's something I want to ask you."
"Go ahead," Kazuma replied, turning to face her.
"Umm…" She smiled awkwardly. "It's about… our relationship."
He knew her name, many of her stories, and even her secrets. The way he treated her was unusual—would a friend really care this much?
Sometimes, Kazuma even looked at her strangely.
As a normal teenage girl, she couldn't help but wonder about romance.
So… are we lovers?
"Lovers?" Under her nervous, expectant gaze, Kazuma gave her a strange look and sighed. "No. We're enemies."
"Huh?!"
The contrast between lovers and enemies was too extreme.
"Tosaka-senpai, you hate me, and you're full of hostility. Once you recover your memories, you'll probably want to skin me alive," Kazuma said seriously. "I'm mentally prepared for it."
Fuyuka was stunned.
"How can that be? If you were my enemy, I should hate you—even with amnesia. But I don't feel that way at all."
"It's hard to say. Who can really know about amnesia?"
She still couldn't accept the idea of them being enemies.
"Could it be… that you did something bad, Kazuma?"
Kazuma looked indignant. "Senpai, do I look like that kind of person? I'm kind and gentle. How could you accuse me?"
"…No, you really don't seem like that type," Fuyuka said softly. "Otherwise, I wouldn't trust you. Even with amnesia, I can tell if someone's good or bad."
She smiled gently.
"It's okay, Kazuma-kun. Even if I regain my memories, I won't hate you or cause trouble for you."
Kazuma's eyes lit up. "You promise?"
"I promise."
The girl made her vow seriously.
"Thank you, senpai. You're a good person," Kazuma said earnestly. "It would be even better if you recorded this promise on your phone."
Fuyuka was speechless. Even though she didn't dislike him, Kazuma's words sometimes made her want to grind her teeth. Still, she pulled out her phone and recorded her promise in front of him.
Relieved, Kazuma crossed his legs and hummed a little tune, making Fuyuka wonder if she had just been tricked. But seeing him so carefree, she couldn't help but smile.
The atmosphere relaxed. The tension eased, and Tosaka-senpai's nerves settled. In the darkness, her gaze stayed fixed on Kazuma, never wavering. After a long silence, she spoke softly.
"Kazuma, why are there no windows here?"
"Oh, I sealed them. Isn't it warmer this way?" Kazuma said casually. This wallpaper room doesn't have windows—it's a four-dimensional space.
"But… I still feel a little cold."
"Then should we cover up with some extra clothes?"
Before he could finish speaking, a faint rustling sound came from beside him. A beautiful girl quietly moved closer to Kazuma. As the distance closed, Kazuma could feel a warm body settling right next to him.
The girl's body heat continued to seep over, radiating a comforting warmth.
Soon after, half of the not-too-thick blanket was pulled over Kazuma, while the other half covered the girl.
"That's fine."
She smiled softly.
"Tosaka-senpai?"
"Shh." She placed a finger against her lips. "It's warm. Go to sleep."
"…"
Tosaka Fuyuka could clearly feel Kazuma's presence and body temperature. His masculine aura seemed to flow toward her endlessly, wrapping around her without restraint. Despite her calm appearance, her heart was racing uncontrollably.
Thump. Thump.
Her cheeks burned fiercely, so red it felt as though you could squeeze tomato juice out of them.
In a mysterious space that did not belong to this world—a fourth-dimensional realm—a boy and a girl lay close together beneath a blanket and gradually drifted into a peaceful sleep. For Tosaka Fuyuka, this was the most tranquil night she had experienced in a very long time.
She didn't know whether it was because of her amnesia,
or simply because Kazuma was beside her.
The next morning, Tosaka Fuyuka was the first to awaken. She immediately realized that she was leaning against Kazuma's shoulder, their bodies pressed tightly together, completely intertwined—and… sigh.
She hurriedly pulled away, covering her chest with one hand as her cheeks flushed red once more.
"Phew… thank goodness he's still asleep. I really shouldn't have hugged him."
Was it because it was too warm… too comfortable?
Sitting beside Kazuma, Tosaka Fuyuka found herself staring at his sleeping face, growing more amused by the second. Unable to resist, she reached out and lightly pinched his cheek. At the same time, a question quietly surfaced in her heart.
"Am I really his enemy?"
Her brows suddenly knit together.
Fragments of unfamiliar memories flashed through her mind, freezing her in place.
She stood up and left the wallpaper room, barely registering the designs lining the walls. Guided purely by instinct, she entered an unfamiliar room. Walking to the window, she stared at the enormous cherry blossom tree standing proudly in the courtyard.
The girl was stunned.
In her vision, it was as if another version of herself stood there, speaking with a boy beside her.
That version of herself held a wooden sword. Her expression was cold, yet a faint sadness lingered deep within her heart. She was on the verge of committing something terrible—until the boy stopped her.
"That's… me?"
Tosaka Fuyuka pressed a hand against her forehead. As for the boy, she recognized him instantly.
"Kazuma-kun…"
