"Ah, Yui-senpai, this way."

"It's been a long wait—"

"It's okay, it's okay, it seems that everyone is here, so let's go."

"Huh? Odd? Didn't Xiao Luo come? ”

"Hmph...... Senior said it was too troublesome, so he didn't want to come. ”

“...... Hawkers, it does look like Xiao Luo would say. ”

"Anyway, I don't care about my predecessors today, let's go, the senior sisters under the snow have been waiting for a while."

"Hmm."

......

The moon climbed into the night sky as if whispering, but in a voice that no one could hear.

Looking into the distance, the light shimmered like stars in the silent darkness.

Suddenly, a spark slowly rose from the ground and exploded in the sky, its shining light turning the sky into a sea of precious stones.

Even from a distance, the beauty remains the same.

"Surprise, fireworks are pretty good......"

"If that's what you think, why don't you go with them, don't you be invited?"

"Then forget it, it's too troublesome, and can't you see it here?"

Luo Tianshu, who raised his head to look at the colorful canvas in the sky and took it all into his eyes, moved his gaze to his side without hesitation, and the blonde girl lying on the railing in the same posture as him-

His sister, Victoria.

"Speaking of which, why don't you read in your room?"

"It's too noisy."

"Haha, huh?"

It's not a reason, but in fact, I just want to see the fireworks.

Luo Tianshu didn't puncture Victoria's random excuses, and the constantly flickering light in the sky caught his attention again.

"If you want to watch the fireworks, it's still too late, after all, it's just the beginning."

"No, didn't you say that? It's the same here. ”

Although the reflection in his eyes was full of colors, Victoria's mouth did not have the slightest acknowledgment.

Because of her height, she looked a little reluctant to lie on the railing, and she needed to stand on her tiptoes to reach it a little easier.

Although there is a small bench a few steps away, it ......

It won't be useful to consider her in any sense, after all, the issue of dignity cannot be compromised.

"Just question."

"Huh?"

Victoria's words made Luo Tianshu come back to her senses from the delusion of the storm in her brain, although her gaze never shifted, Luo Tianshu could feel that the other party's attention had shifted to her.

"Why didn't you agree to their invitation, if it was too troublesome, what are you doing now?"

"It's different."

Lowering his body slightly, Luo Tianshu let his head move closer to Victoria.

"I like a little more relaxed environment."

"What? Does it make you feel hard to be with them? ”

"Of course not."

Denied the inference that Victoria said, Luo Tianshu seemed to suddenly realize something, and looked at the other party with a hint of banter in his eyes.

"Hey, what's wrong? Because my brother didn't come home last night, are you jealous worriedly? ”

Hearing this, Victoria frowned, and her mouth instantly became merciless:

"Boring, you delusional idiot, who's your sister."

"Isn't that you?"

“...... Hum. ”

After an ambiguous response, and leaving behind such an ambiguous attitude that neither denies nor agrees, Victoria unilaterally ended the subject.

Or skip it.

“...... I said you, the other day, why do you do so much redundancy? ”

"A few days ago?"

Luo Tianshu looked at Victoria in confusion, the other party didn't speak, didn't explain anything, just looked at the flowers blooming in the night sky.

"Could it be that you're talking about identity?"

Luo Tianshu tried to guess.

"Hmm."

Victoria nodded, even though her already small voice seemed more difficult to catch because of the fireworks, Luo Tianshu still heard what she said clearly.

"That's not something important, is it? For me, who doesn't belong to this world in the first place, identity is not so much redundant as unnecessary, right? ”

"There's no need...... Something is wrong, but there is still a lot to use for this thing. ”

“......”

Luo Tianshu did not continue to hear the follow-up of Victoria's question, but instead the other party's calm gaze that stayed on him.

Under the light of the fireworks, the eyes of the two briefly intertwined, this time, it was Luo Tianshu who chose to end, but the end was not the topic, but the perfunctory way of answering.

"What's wrong? Not satisfied with this promise? ”

"You said it......"

Victoria looked at Luo Tianshu and said word by word:

"We don't lie to each other, that's what you said, right?"

"That's right."

Faced with Victoria's almost kidnapping question, Luo Tianshu admitted very calmly:

"We don't lie to each other, because there's no reason and no point, so what?"

"So, I want to know the real reason why you did that."

“......”

Even though Victoria needed to look up at Luo Tianshu because of her low stature, the seriousness in her eyes was not low at all.

"The real reason......

Luo Tianshu looked away, but he didn't mean to avoid it, and his gestures looked a little strangely comfortable.

was silent, and it wasn't until the fireworks that lifted off for the second time lit up Luo Tianshu's eyes looking at the night sky again that he heard him say lightly:

"Because, you're a sister."

"Ah......?"

Victoria was stunned, what Luo Tianshu said was not an obscure code word, but it was precisely because of this that she felt puzzled.

"What does that mean?"

"Literally, because you're a sister."

“...... It's as simple as that? ”

"It's as simple as that, because you're a sister."

Repeating the same words, the corners of Luo Tianshu's mouth slowly hooked.

"Although you guys are not cute at all, and often cause me trouble, ruin my home world, and often make me unable to stay at home as a NEET, but ......"

A series of complaints made Victoria's brain even more confused, and he didn't know whether to be angry or not, so he only heard Luo Tianshu continue:

"We are brother and sister."

“......”

"I'm an elder brother and you're a younger sister, this is a fact that can't be changed, although in terms of blood, race, and even the original world, our 'brother and sister' are completely unreasonable existences, but unfortunately, the established facts can't be changed."

Luo Tianshu slowly turned his head to meet Victoria's gaze,

"It's because of that irrationality that is bound to exist no matter what, that in this world, we are brother and sister, aren't we?"

“......”

Victoria was silent, just staring at Luo Tianshu quietly, since the first time the two met, although they have built a unique "relationship" with each other in a short period of time, but in fact, both of them will subconsciously and deliberately avoid this kind of topic.

There is no special reason, it's just that Victoria doesn't ask, and Luo Tianshu doesn't say it.

Over time, this became an unwritten tacit understanding between the two, but with the incident a few days ago, Victoria wanted to ask on a whim, no, this should not be a whim, but .......

"Before, I had an older brother."

"This is the first time I've heard of it."

"Although it's my brother, but the relationship between us is not so good, it's just that I don't like it, and I can't talk about the level of hate."

"Ordinary, this is really unexpected."

"It's not just my brother, all my family, yes, all my family is the same for me, even if suddenly one day they don't see each other, I'm afraid I won't feel anything."

Under the brilliant fireworks, Victoria's lonely eyes flashed away.

"So, I never knew what kind of existence I had for others."

“......”

"'We are brother and sister,' that's what you say."

Victoria looked at Luo Tianshu's calm gaze, and at this moment, there was a little hope.

"So, can you take responsibility for this statement?"

"Responsibility?"

"I haven't seen them for sure, so I don't know what an ordinary brother and sister look like, but according to the book, the so-called 'brother and sister' generally live together for a long time, right?"

"That's true."

"That ......"

With a slight gaze, Victoria's small hand at his side gently grabbed the hem of his clothes:

"Will you always be by my side for a long time from now?"

The night breeze blew long bangs, Luo Tianshu smiled faintly, his gaze was never more serious:

"Didn't I run out of choices for a long time? Because now we are brothers and sisters. ”

"That's right......"

As he spoke, his long golden hair began to flutter in the wind, and Victoria took the initiative to approach Luo Tianshu and gently took his hand.

"Then, what you say counts, brother."

"Well, I will, sister."
