The Rare Magic Hall had always felt larger than it truly was, not because of its size, but because of the power resting quietly within it. Layers of formations were embedded into the polished stone floor, faint geometric patterns overlapping like a silent language only mages could read. A translucent barrier shimmered high above, almost invisible unless light caught it just right, and the air carried a low hum, soft and steady, like something waiting.
Today, that hum felt heavier.
Yung Yu stepped into the central circle without hesitation, and the formation beneath him responded at once. Pale lines glowed beneath his boots, acknowledging his presence as if the hall itself recognized the weight of his mana.
I moved to stand opposite him, careful but not rigid about the distance between us. Too close, and our magic would press against each other unnecessarily. Too far, and I wouldn't be able to react in time. There was always a balance to be found, and Space Magic, more than anything else, was about understanding where that balance lived.
Professor Lin positioned himself near the outer edge of the hall, hands folded calmly behind his back, his expression unreadable.
"Today," he said in his even, unhurried tone, "we are not testing strength. We are testing tolerance."
Tolerance.
Not dominance. Not power.
How much two forces could endure in proximity without breaking.
I drew in a slow breath.
Ever since I had realized I was inside a novel, moments like this felt sharper somehow. Training sessions weren't just practice anymore; they were foundations for future events. In the original story, Yung Yu had struggled alone with his Dark Magic. He had pushed himself too far, too often, trying to achieve perfection through sheer will, and more than once, that had ended in injury.
That wasn't happening this time.
Because I was here.
And I still didn't know whether I was changing fate for the better, or simply interfering with something that was meant to unfold.
"Begin with compression," Professor Lin instructed.
Yung Yu closed his eyes.
Dark Mana gathered around him slowly, not wild or explosive, but dense and deliberate. It folded inward toward him, condensing closer and closer to his core, like a shadow thickening at sunset. The air around him seemed to grow heavier, quieter.
I felt it immediately.
Dark Magic wasn't chaotic. It wasn't reckless.
It was absolute.
It didn't argue with the space around it,
it simply claimed it.
The formation lines beneath him flickered faintly as the pressure increased. His posture remained steady, but I noticed the subtle tension along his jaw, the way his fingers curled ever so slightly.
He wasn't afraid.
He just refused to fail.
In the novel, he had been described as a perfectionist, someone who would rather break than accept imperfection. Watching him now, I could see it clearly. He wasn't testing his limits:
he was trying to force them further.
The compression tightened.
The air between us thinned, and a faint crackling sound echoed through the hall as the formation resisted the growing pressure.
"Expand," Professor Lin said calmly.
Yung Yu released the condensed mana outward in a controlled pulse.
It collided with the surrounding formation, and the barrier above shimmered in response. The impact rebounded almost instantly, pushing back toward him with sharp intensity.
Too fast.
If left alone, the recoil would grow unstable.
I exhaled softly and let a thread of Space Magic slip from my fingertips, not toward him, but around him.
Instead of touching his power directly, I allowed my mana to settle like a second skin around the edges of his Dark Magic, widening the space just enough so that the impact wouldn't snap back violently. It was less about stopping the force and more about giving it somewhere to breathe.
The harsh ripple softened.
What might have rebounded into chaos instead spread outward in a smoother wave.
Yung Yu's eyes opened immediately, and they locked onto mine.
He felt it.
Of course he did.
"You adjusted it," he said quietly.
"Yes."
"You didn't interfere."
"I didn't need to."
I would never step into his control channels without permission. Supporting him was different from controlling him, and that line mattered.
Professor Lin's gaze sharpened slightly. "Again."
This time, Yung Yu compressed faster.
Dark Mana gathered more sharply, almost visible as a distortion in the air, like heat rising from stone. The formation flickered harder, and a faint, strained sound split the silence.
He was pushing too much into too little space.
Why?
Because he didn't trust that anything outside himself would hold.
Because, in the original story, nothing ever had.
Something tightened in my chest.
I stepped forward before I consciously decided to. This time, I extended more than one thread of Space Magic, letting it flow outward in a gentle arc that wrapped around his rotating mana like a protective current. I didn't press against it. I didn't force it inward.
I simply surrounded it.
Where the pressure grew too sharp, I softened the edges. Where the energy strained against the formation, I curved the space around it so the impact would slide instead of collide.
It was like cupping water in my hands without closing my fingers.
The crackling eased.
The distortion smoothed.
Yung Yu inhaled slowly, and though he didn't look at me, I felt the subtle shift in his control. Instead of forcing more power outward, he adjusted, guiding the flow downward and redistributing it through the formation lines.
He was adapting.
"Increase rotational speed," Professor Lin instructed.
The Dark Mana began to turn around him, slowly at first, forming a controlled orbit that circled his body in a steady rhythm. As the rotation accelerated, the air vibrated with a low hum that pressed gently against my ribs.
The faster it moved, the more strain built at the edges.
This wasn't about blocking impact anymore.
It was about harmony.
I let my Space Magic move with his instead of against it, shaping the surrounding space so his mana had room to rotate freely. Rather than resisting the friction, I smoothed the path ahead of it, guiding the flow so it wouldn't scrape harshly against the formation's boundaries.
Gradually, the hum softened.
The flickering stopped and the rotation steadied.
For a brief moment, it was almost beautiful,the dark current moving in controlled circles, contained yet powerful, no longer fighting its environment but existing within it.
Yung Yu's eyes widened ever so slightly.
He felt it too.
This wasn't suppression.
It was support.
He increased the speed again, deliberately this time.
A silent challenge, as if saying:
Can you keep up?
My pulse quickened, but instead of reacting with force, I closed my eyes for a second and simply listened. Mana had patterns. It had rhythm. If I forced my own over his, everything would fall apart.
So I aligned with his rhythm.
I let my threads follow the natural curve of his power, adjusting gently whenever the strain rose too high, easing it before it could become sharp.
The vortex smoothed further, settling into a stable, steady motion.
"That is sufficient," Professor Lin said at last.
Yung Yu's Dark Mana collapsed inward and faded, leaving the hall in sudden quiet.
Only then did I realize how tightly I had been holding my breath.
He studied me again, but this time there was no guarded edge in his expression, only assessment.
"You anticipated the rebound before it formed," he said.
"Yes."
"How?"
I hesitated, searching for words that weren't too revealing.
"It felt… wrong," I admitted softly. "Like the space around you was about to tear. And I reacted."
His gaze sharpened slightly.
"You analyzed my pattern."
"Maybe," I replied. "You compress too much before you expand. Your control is strong, but the transition is where the strain builds."
There was a brief silence.
I met his eyes.
"If you ever destabilize," I said carefully, "I can hold it long enough for you to regain control."
The words slipped out before I could soften them.
"I don't plan on losing control."
"I know," I whispered.
But plans didn't matter in stories.
Events did.
Professor Lin stepped closer, breaking the tension between us. "You will continue this coordination once a month," he said calmly. "And Lianmei, refine that anchoring technique. It can stabilize far more than Dark Magic."
Far more.
I felt it too. The depth of my Space Magic was still something I was only beginning to understand. There were layers I hadn't touched yet, currents beneath currents, something vast and sleeping within me that I could sense but not fully grasp.
One day, I would.
As we left the hall, Yung Yu walked beside me,
not ahead and not behind.
"Next time," he said without looking at me, "increase the pressure earlier."
I blinked. "You want me to intervene sooner?"
"I want you to trust your judgment."
The words settled somewhere deeper than I expected.
Trust my judgment.
In a story I was trying to rewrite.
"…Alright," I said softly.
For the first time, our steps fell into the same rhythm.
Not as leader and support.
Not as male lead and side character.
But something closer to balance.
