Grand Return System

A Smile That Meant Too Much

"Junior Brother, this move must be very powerful, right? Is it a God-grade Sacred Art?"

Maya couldn’t make sense of it no matter how she turned it over in her mind. The more she thought about his words, the stranger they felt—too layered, too vivid, almost... personal.

So she gave up trying to decode it alone and simply asked.

Her voice was softer now, curiosity wrapped with something faintly restless.

Leon looked at her.

Then he smiled.

A slow, easy smile—like he already knew exactly where her thoughts had wandered.

"I think so."

He said it casually, almost lazily.

But there was weight behind it.

The kind of weight that didn’t need explanation.

Because to him... that moment, that "technique"... it was sacred.

More than sacred.

Maya’s eyes lit up instantly.

So I was right...

A God-grade Sacred Art.

Something jumped inside her chest, not from being scared, but from a sudden spark. Raw wonder, nothing held back. That pull toward the unknown tugged her forward before she even noticed.

A soft grin lifted one corner of her mouth, while light bent gently through her narrowed eyelids. Moon-shaped arcs formed above cheeks that warmed without warning.

"Junior Brother... when are you going to demonstrate this God-grade Sacred Art to me so I can broaden my horizons?"

Her voice carried a quiet truth. A kind of honesty that felt rare.

And something else.

Something softer.

Leon blinked once—just once.

Then that smile on his lips shifted.

Not wider.

Just... sharper.

More dangerous.

Out there, past the edge of the sand, faces blurred into a hum of motion and sound. His look moved slow, catching flickers - someone shifting, a hand raised mid-air. Noise pressed close, thick with breath and waiting. Eyes stuck to him, scattered yet sharp, like points of light in uneven rows.

Close by now, he dropped his voice a notch.

"That’s not a good idea, Senior Sister..."

Quiet now, his voice slipped into something closer, softer.

"There are too many people here. It would be... embarrassing."

For a moment he stopped, eyes fixed on how she responded.

After that came a pause, each moment stretching out like taffy pulled thin

"If you really want to see it... we should find somewhere quiet."

A shift passed through his gaze, too quick to name.

"I can show you properly. Step by step... how the technique moves, how it breaks through defenses... how every motion flows."

A beat.

"I’ll demonstrate it to you personally... if you want."

Maya’s breath hitched—just slightly.

"Really?"

She didn’t even realize how quickly she asked.

There was no suspicion yet.

Only anticipation.

Leon chuckled softly, completely at ease.

"When have I ever lied to you?"

He tilted his head, studying her expression.

"How could I refuse if a beautiful, cute Senior Sister wants to see it for herself?"

That did it.

Her eyes brightened even more.

She didn’t think too deeply about it. Why would she?

A God-grade Sacred Art wasn’t something you casually displayed in public. Of course it required privacy. Of course it needed trust.

And he chose her.

That thought alone warmed something deep inside her chest.

So... I still matter to him.

A small, quiet happiness bloomed.

Unnoticed.

Uncontrolled.

For a fleeting second, she even had the absurd urge to step closer—maybe even hug him in excitement.

But she held herself back.

Barely.

After all—

That was a God-grade Sacred Art.

Even as a Division Master, the highest level she had ever truly grasped was only Earth-grade.

Heaven-grade techniques?

She had never even touched one.

There simply weren’t any in the Holy Water Division’s inheritance.

In the entire Celestis Academy, aside from the Headmaster’s exclusive technique... only the Amethyst Summit Division was rumored to possess anything above that level.

And Leon...

He just casually spoke about it.

Where did he even get something like this?

Her thoughts raced.

Maybe... his Division’s legacy runs deeper than we thought.

She exhaled slowly, trying to steady herself.

Then, cautiously—

"Then... let’s agree. When we have time today... we’ll find somewhere quiet, and you can demonstrate it to me?"

Her voice carried a hint of expectation.

And just a trace of nervousness.

Leon’s smile deepened.

"Sure."

He didn’t hesitate.

"I can’t ask for more..."

There it was again.

That smile.

Maya’s lips pressed together slightly.

Her expression shifted.

Why does it feel like...

...his smile isn’t clean?

A strange feeling crept into her chest.

Unsettling.

Familiar.

Dangerous.

Her heartbeat quickened as fragments of their earlier conversation began to resurface.

Strolling across plains... touching stars... diving into depths... breaking through...

Her pupils trembled.

Wait...

Her thoughts stalled.

Then—

Connected.

Everything.

"...No way..."

Her face turned red in an instant.

From neck to ears.

Burning.

Her lips parted, but no sound came out at first.

Then, in a small, shaken voice—

"Lo... love... making...?"

The realization hit her like lightning.

She froze.

Then collapsed internally.

Completely.

"Ah... so this bastard was talking about that..."

Her mind blanked.

She had just—

Just spent all that time—

Seriously discussing it.

Analyzing it.

Even asking to see it demonstrated.

And not just anywhere—

A quiet place.

Alone.

Her entire body stiffened.

Maya’s face turned even redder.

If there were a hole nearby, she would have jumped into it without hesitation.

How did I not notice...?

How did I say that out loud...?

Leon, meanwhile, was holding back laughter with visible effort.

His shoulders trembled slightly.

His eyes curved with amusement.

Teasing her like this...

...was way more fun than he expected.

This Senior Sister—so composed, so elegant, always in control—

And yet here she was.

Completely undone.

He suddenly thought—

Maybe I should teach her a few things properly someday...

Leon cleared his throat lightly, forcing his expression back to something serious.

"Senior Sister, what’s wrong?"

He tilted his head slightly.

"Why is your face so red...?"

That was it.

Her breaking point.

"Go to hell! You... you—"

She couldn’t even finish the sentence.

Her words tangled, her thoughts worse.

"I’ll never talk to you again!"

She turned and fled.

Actually fled.

No dignity.

No composure.

Just panic.

And Leon stood there, watching her retreating figure—

Finally letting out a quiet laugh.
