The Butterfly Effect.
The delicate flutter of a butterflyâs wings... a simple act that could set off a chain of events powerful enough to create a storm. A poetic metaphor, often used to illustrate how seemingly insignificant actions can lead to monumental consequences.
For a time traveler, however, this idea holds far greater weight.
A choice as small as a grain of sand, made in the distant past, could reshape the entire fabric of the future.
Until now, Flame had been completely unawareâ
Unaware that she had been ensnared by Silver Autumn Moon, caught in a relentless cycle of the same event, replaying it fifty times.
However, the faint dĂ©jĂ vu she experienced hinted at somethingâ
A shift.
Countless trials and errors.
Endless repetitions.
And at the end of it all...
A coincidence.
Coincidences, by their nature, seem improbable, fleeting as stars in the daylight. Yet improbability does not mean impossibility.
If the same event were to repeat enough times, even the most improbable coincidence could eventually occur.
And this moment - right now - was that moment of coincidence.
Florin was captured by Dusk Soil Moon.
Eisel raced toward her with reckless determination.
Flame chased after them both.
... But that wasnât all.
Hong Bi-Yeonâs death.
Jelielâs disappearance.
The exchange program delayed by a single day.
French fries on the lunch menu.
A forgotten handkerchief this morning.
Left foot stepping forward instead of the right.
Even the type of socks worn today.
Every small detail - woven together into an intricate chain of events - had culminated in this one timeline, where Dusk Soil Moonâs awakening could be stopped.
At a glance, these incidents might seem like insignificant occurrences.
But in this moment, it was clearâ
This scenario was a one-in-a-million eventâ
A singular point that could only occur through countless repetitions across infinite timelines.
â... I didnât end up here by coincidence.â
Flame knew this for certain.
So, she pushed herself to run faster.
To save Florin and the World Tree.
To reach the future.
To return to Baek Yu-Seol.
"Wait!!"
Flameâs steps came to an abrupt halt.
When she turned around, she saw Silver Autumn Moon, his figure shimmering like a mirage, staring at her with desperation.
"Wait, Flame..."
"...Silver Autumn Moon."
For a moment, he said nothing. His lips pressed into a firm line as his gaze locked onto hers, the weight of unspoken words hanging between them.
Time seemed to freeze. The air around them grew heavy, and the world fell into a suffocating silence.
But thenâ
Flame stepped out of that stillness and gave him a gentle smile.
"Iâm sorry."
"WaitâFlame...!"
She took a step back.
Silver Autumn Moon cried out urgently.
"I need you! I canât be without you!"
He was, in some ways, a truly pitiful soul.
A Twelve Divine Moon who had lived for thousands of years, yet had fallen for a human who wouldnât even live a hundred.
Even though Flame was the object of his twisted love, she couldnât bring herself to hate him.
Yes, he was the one who had trapped her here, keeping her from returning home.
Yes, he deserved to be cursed for what he had done.
But for some reason, Flame couldnât bring herself to do it.
The pain he endured - the inability to even approach the one he loved - was a suffering she couldnât bring herself to crush.
â...How tragic.â
That was all she could feel.
With a heavy heart, Flame turned back, preparing to run toward Eisel once again.
But thenâ
"... Please."
His voice trembled, raw and desperate in a way she had never heard before.
"Our world... needs you. We absolutely need you!"
This time, his tone felt different.
âNeed?â
Flame blinked, confused by Silver Autumn Moonâs strange words.
Sensing her hesitation, he quickly repeated himself.
"If youâre not here, our world will be destroyed! Are you trying to kill all of us?!"
"What? What are you talking about...?"
It didnât make sense.
"Even if I go back... The Flame who originally lived in this world will still be here. Sheâll figure something outâ"
"Nonsense!"
Silver Autumn Moon interrupted, his voice trembling as if the weight of the truth was too much to bear. Tears shimmered in his eyes, threatening to spill.
"There is no âother Flameâ in this world!"
"That canât be... You told me yourself, thereâs another version of me in this world..."
A lie.
Flame wanted to believe it was all a lie.
But the desperation on Silver Autumn Moonâs face, mixed with tears, showed no signs of deception.
"... That was a lie."
"And how can I trust what youâre saying now isnât a lie too?"
Silver Autumn Moon shook his head.
"Youâve seen it too, havenât you? Thereâs no such person as Baek Yu-Seol in this world."
"Th-Thatâs..."
It was strange, no doubt.
Why didnât Baek Yu-Seol exist in this world?
At first, she had thought it odd.
She had noticed discrepancies... the schoolâs student count was one higher in this world, suggesting Baek Yu-Seolâs presence wasnât native to the novelâs setting but tied to this timeline.
However, when she learned that Baek Yu-Seol had come from Earth, just like her, the anomaly seemed explainable.
"But unlike Baek Yu-Seol, Iâve clearly existed in this world from the beginning. I enrolled at Stella long before I arrived here, and plenty of people recognize meâ"
"How can you be so sure?"
Silver Autumn Moon gave a bitter laugh.
"You, Flame... no, all of you who step into this world are special. The moment you arrive, this world rewrites its memories. It bends its reality to make it seem as if youâve always been here. And then..."
A lifeless leaf fell to the ground and shattered.
"When you disappear, we all forget you ever existed. ...And as you already know, a world without âFlameâ is destined to collapse."
It was the undeniable story of the original novel, Do Not Love the Unfortunate Princess.
In that story, Flame didnât exist, and the world was destroyed.
"Thatâs right, Flame. It has to be you."
"What are you talking about...?"
"You donât actually believe thereâs only one or two worlds like ours, do you?" His gaze bore into hers, piercing her soul. "No, you already know the truth. I can see it in your eyes. Youâve glimpsed the windows of time... Youâve seen countless pasts, havenât you?"
He wasnât wrong.
Flame had briefly witnessed Baek Yu-Seolâs regressions during the Constellation Project.
By observing those events, she had come to understandâ
This world wasnât unique.
It was just one of many.
Rumble...!!!
The tremors of Dusk Soil Moon grew more intense.
With Eiselâs arrival, a new possibility had opened.
All Flame had to do was run forwardâ
And she could return to the future.
Yet, her feet wouldnât move.
â...This is it.â
The truth she had sought, even after being sent back in time.
âWhy do I exist in this world?â
âAnd... What am I supposed to do?â
Her lips trembled as she forced herself to speak.
"If I stay here... Does that mean the world wonât be destroyed?"
Silver Autumn Moon instinctively started to nod, but then he hesitated.
When he averted his gaze, Flameâs expression crumbled.
"So... itâs not guaranteed the world wonât be destroyed?"
"Right...?"
Silver Autumn Moon squeezed his eyes shut, trying not to answer.
But when Flame pressed him again, he could no longer hold backâ
And in the end, he nodded.
"Thatâs right... You canât guarantee saving our world. Youâll face countless failures and repetitions. Youâll fail again and again. And maybe... The probability of you saving this world will approach zero. You might have to keep running endlessly, clinging to the slimmest chance of success."
Just like Baek Yu-Seol.
"Thatâs..."
She couldnât believe it.
Of course, she had no memories of regressing.
Flame had simply fallen into the world of a novel she enjoyed reading.
"That canât be true. I donât have any memories of that."
"Exactly."
Silver Autumn Moon gave a bitter smile.
"Someone like you - a radiant, extraordinary being - couldnât possibly have had your memories completely erased by someone like Fawn Prevernal Moon. Unlike Eisel or Hong Bi-Yeon, the only memories erased from you were those right before your time travel. And even those were fragile shattered by the slightest shock."
Her memories werenât erased.
Then...
"Thatâs all I can tell you, Flame."
Silver Autumn Moon reached out his hand.
"Your world has Baek Yu-Seol. That boy will definitely save your world. So... why donât you stay here? Itâll be hard, and itâll take everything you have, but if you stay... we can have hope again."
It sounded convincing, even tempting.
And he wasnât wrong.
That worldâ
âBaek Yu-Seol will save it.â
But this world?
It was just one world among countless others.
Yet it was a world she had seen, felt, and experienced with her own eyes.
She couldnât just walk away.
"But I..."
She had to go back.
Boomâ!!!
Suddenly, the situation shifted.
Dusk Soil Moon began to thrash violently as if Eisel had done something.
Meanwhile, Florin was freed from her restraints and was no longer having her life force drained.
The situation was changing fast.
She had to make a choice.
Noticing Flameâs hesitation, Silver Autumn Moon took a step closer with an almost pleasing expression.
"Come with me, Flame. Iâno, weâcan protect you."
"I..."
At that momentâ
She suddenly felt something tugging at her elbow.
Startled, she quickly turned around, but there was no one there.
Instead, what filled her field of vision left her feeling utterly dumbfounded.
Somehow, Eisel had already climbed to the very top of Dusk Soil Moon andâ
Like a mountaineer planting a flag after conquering a peakâ
She had planted her staff into the massive creatureâs head and was now freezing its entire body solid.
"Ahahahaha! Iâm going back hoooome!!"
Eisel laughed and beaming brightly as she raised her staff in triumph.
Butâ
That wasnât the 17-year-old, first-year Eisel.
No.
The playful smirk and the overwhelming cold mana, far beyond what a Class 3 student could wieldâ
This was undoubtedly the future Eisel.
Even the line she just shoutedâ
Hadnât Flame personally taught her that?
â...Of course.â
There was no time to question how this impossible event had happened.
Insteadâ
"...Iâm sorry, but I have to go back."
Flame gave Silver Autumn Moon a bittersweet smile before turning away and racing toward Eisel.
âIâm selfish.â
But she didnât think that was wrong.
In fact, it was only natural.
Wasnât it?
Silver Autumn Moon had preyed on her moment of weakness, trying to force her to sacrifice herself.
He, too, was selfish.
And if both sides were being selfishâ
Then the one with the right to choose should take what they wanted.
Flame ran.
She ran with everything she had.
She couldnât remember how far or how long she ran.
All she knew was that she poured every ounce of strength she had into reaching Eisel, and when she did, she pulled her into a tight embrace.
The world was suddenly engulfed in light.
Dusk Soil Moon, the World Tree, Florin, Silver Autumn Moon, the sky, and the earthâ
Everything began to fade away into the distance.
"I curse you, Flame!!!"
But one voice remained.
Silver Autumn Moon refused to disappear quietly.
He shouted at Flame, his voice echoing through the void.
"Because of you! Our world will be destroyed! You killed it! Every living being in this worldâyou killed them all!!"
Flame squeezed her eyes shut.
His words were like knives, stabbing deep into her chest.
"You... abandoned meâabandoned our worldâand you think you can just return peacefully?! Donât even dream of it! Flame, I curse you! You will never return to your world!!"
"Ugh...!"
Thud!
Silver Autumn Moon let out one final anguished cry before disappearing.
His curse struck Flame head-on, and she collapsed to her knees within the blinding white void.
"Hic... ugh...!"
Something felt wrong.
Her stomach churned, and her head pounded in unbearable pain.
Her legs began to weaken, and just as she was about to fall completely,
Two arms suddenly caught her, holding her up.
Startled, Flame quickly looked upâ
And saw familiar faces smiling down at her.
âWhat took you so long? Seriously.â
Eiselâs voice.
â...Youâre disgustingly late.â
Hong Bi-Yeonâs voice.
Even amidst the blinding light that surrounded them,
Flame could see Eisel and Hong Bi-Yeonâs smiles.
Butâ
Flame couldnât bring herself to say anything to them.
âIâm sorry... Iâm so sorry... because of me... So much had happened. So much.â
Trapped in the past, her memories lost, and manipulated by this worldâs Silver Autumn Moon... It forced to repeat the same time loop dozens of times.
And as if that werenât enoughâ
âNow the door to the future is completely sealed. Ha...â
âHah, this worldâs Silver Autumn Moon is so petty. Totally different from the one in our world.â
Now, she couldnât even return home.
Silver Autumn Moon must have pulled something at the last moment.
But knowing that didnât change the fact that there was no way out.
âWell... itâs fine. At least this is better than being trapped inside another Eiselâs memories, manipulated against my will.â
â...I even burned to death several times. I lost consciousness right before dying, so I canât remember it... But Iâd still choose this over repeating that nightmare.â
Even as Eisel and Hong Bi-Yeon tried to stay positive, it didnât change the reality of their situation.
âNo... This is my fault.â
In the end, the one who caused all of this was herself.
âBecause of me, all of you...â
"Flame."
She looked up.
âThank you.â
â...What?â
âThanks to you, I realized just how lucky Iâve been. And how much all the people who reached out to me truly meant in my life.â
â... Thatâs...â
âDonât say something so pointless.â
âHeh, Hong Bi-Yeon... you feel the same, donât you?â
Hong Bi-Yeon didnât respond.
But her silence was as good as a yes.
Feeling somewhat comforted, Flame let out a faint frown.
Then, as if suddenly remembering something, Eisel spoke up.
âInstead of worrying, letâs try the spell."â
â... A spell?â
âYeah.â
âBut... That wonât work anymore.â
The path was completely blocked. At this point, reciting the spell felt meaningless.
Yet, Eisel quickly pulled her up, as if to say, âLetâs just try it.â
â... Fine. Letâs give it a shot. You two... You remember the spell, right?â
âOf course.â
âIdiot commoner. Everyone remembers it except you.â
Flame couldnât help but smile.
The truth was, she remembered it now too.
It was such a simple, heartfelt spell that she couldnât even understand why she had forgotten it in the first place.
And soâ
The three girls locked eyes, and in unison, began to recite the spell.
â...Letâs go backâto where the people we love, and the people who love us, are waiting.â
... Silence.
As expected, nothing happened.
The girls exchanged bitter smiles, looking at one another.
Before Flame could say anything, Eisel spoke first.
âWell... itâs better than not trying at all. At least weâve ruled out one option, so now we can focus on thinking of something else.â
Then Hong Bi-Yeon chimed in.
âStop making that miserable face. Itâs not your fault, okay? I followed you here because I wanted to. So why do you look like someoneâs dying? Are all commoners this dramatic? Iâll never understand them.â
â... Haha...â
Flame laughed weakly.
She wasnât even sure what they were doing anymore.
Crying and getting comforted by her friendsâ
It was so unlike Flame.
âYeah. Thanks. Even if we canât go back... weâll never give up.â
Thatâs what she wanted to say.
Butâ
â...Huh?"â
Both Eisel and Hong Bi-Yeon suddenly froze, their eyes wide and mouths agape, staring at something behind her.
They looked shocked.
Flame quickly spun aroundâ
And there, stepping through the cracks in the glowing light, was Baek Yu-Seol.
"Itâs been a while, troublemakers."
âB-Baek Yu-Seol...?!â
âHow... Are you here...?â
â... And why are you so late?â
Her legs almost gave out.
But she somehow managed to hold herself together with sheer determination.
She didnât want to look weak in front of him, not anymore.
Baek Yu-Seol stepped fully through the radiant portal, pushing it open wide.
Then, pointing back toward the world behind him, he grinned.
"Loving someone, huh? Iâm curiousâcare to tell me about it on the way back?"
