This wasn’t Roy’s first time entering Sister Elsa’s room.

But it would certainly be the most unforgettable.

After all, in this small, cozy space…

He was about to share his very first night.

His first time sleeping beside Sister Elsa.

A strange mix of emotions swirled in the boy’s heart.

After all—who else could know?

That this curvaceous, airheaded nun before him—

Whose name had been untarnished by sin before meeting him—

Would one day become the "Radiant Nun."

Blessed by the Goddess of Light.

A vital member of the Hero’s party, bound by the grand duty of "saving the world."

And Roy himself?

How utterly theatrical it was…

That he would become the very one she’d one day hunt down.

His Majesty the Demon King.

The "source of all evil in the world."

Two souls seemingly destined to stand as mortal enemies.

Yet here they were—both trembling with shyness and nervousness.

*Click.*

The sound of the lock turning made Roy flinch.

His gaze snapped from the room’s furnishings…

Straight into Sister Elsa’s pale blue eyes.

"Elsa… Sister?"

Why lock the door?

It felt like she was afraid… he might run away.

This side of Sister Elsa felt…

A little scary.

But also… kind of fun, wasn’t it~?

"S-sorry! It’s just… my habit!"

Elsa only just realized she’d locked the door without thinking.

Roy’s question flooded her with embarrassment.

*What am I even doing?!*

Wasn’t this supposed to cure his insomnia?

Why did she look like some wicked older sister about to devour a little boy?!

Locking the door—was it to stop this adorable, sweet-smelling, utterly irresistible boy from escaping?!

*Elsa, get a grip!*

To hide her fluster—and deeper, secret feelings—

She committed a sin against the Goddess.

She broke the nun’s vow of honesty.

Blurted out an excuse.

Or rather…

A lie.

She had no such habit of locking doors before bed!

But the guilt over betraying the Goddess paled…

Beside her terror of Roy hating her.

Of him seeing her as some weird, chesty auntie with indecent thoughts!

If her image shattered in his eyes over this… Elsa would fall apart completely.

"I see."

Roy accepted her explanation easily.

His bright, sunny smile dazzled Elsa—almost painfully so.

Compared to Roy’s pure innocence…

Her own adult thoughts felt filthy.

Shame burned her cheeks.

Luckily, Roy didn’t notice her flush.

His eyes drifted to her desk.

Gospel books from the Radiant Church lay neatly beside pens and paper.

In the top-right corner, a delicate ceramic cup held…

Cold tea. Yet its unique fragrance still lingered.

A scent that calmed the mind and soothed the soul.

Elsa clearly took her duties seriously.

Few would memorize entire gospel texts about the Goddess of Light these days.

True believers were rare in this age of fading miracles.

And among them, Sister Elsa’s devotion…

Was why the Goddess had chosen her.

To become the future Hero.

*Of course… only if Roy hadn’t interfered.*

Without him in her life…

She’d have remained the most pious nun at the Radiant Convent.

Not someone constantly dragged into the confessional booth these days.

This young Demon King truly scrambled one’s "cultivation heart."

Letting him "cultivate" her seemed only fair.

Roy stepped toward the desk.

His violet eyes traced Elsa’s neat, slightly messy handwriting.

Very much her style—ink smudges and crossed-out words everywhere.

He could almost picture her sitting upright, diligently writing…

Only to have her ample bosom block her view,

Causing accidental slips of the pen.

Even Roy, with his iron will, nearly smiled at the thought.

His gaze then shifted to the plain ceramic cup beside her.

Wrinkled, rust-red tea leaves floated in the cooled water.

The aroma remained deep and comforting.

Roy feigned pleasant surprise.

"So you’ve been drinking the tea I gave you."

"It’s just… wild tea from my hometown. Worth nothing."

He spoke of home with shy humility.

The picture of a simple country boy.

"It’s not about worth," Elsa said, cheeks flushing. "It’s about who gave it."

"Besides… Roy’s tea really is delicious."

"And it helps me sleep."

"Sometimes I’m exhausted, but my heart feels heavy… sleep won’t come."

"Then… your tea stays with me through those hard nights."

*And not just the tea.*

*Roy himself—both in dreams and waking life—*

*Has carried me through the darkest hours.*

That was why his presence weighed so heavily in her heart.

Elsa hadn’t always been strong.

She’d learned to be strong.

Forced herself to be strong.

After Mother and Father "left"…

Only she and her little sister Airi remained.

Airi had only her.

She had to fight for survival. Had to endure everything.

No one seemed to notice how tired she was. How fragile.

How she’d curl up alone in the dead of night, knees hugged tight,

Silently crying so Airi wouldn’t hear through the thin walls.

Day after day, the mask of bravery became her skin.

She’d almost forgotten she didn’t *have* to be strong.

That she, too, had the right to be weak…

Until the boy showed her.

One evening, exhausted after leaving the convent,

A black-haired, violet-eyed boy nervously blocked her path.

The new neighbor kid—Roy, was it?

"Can I help you with something…?"

Elsa hadn’t known him well then. She offered only a practiced, hollow smile.

She thought he needed assistance.

But the boy cut her off.

"I don’t need help."

"I just think… Sister should care for herself more."

"Eh…?"

"You always help everyone selflessly."

"But no one sees how hard it is for you."

"I don’t understand why."

"But I remember you helping me move."

"So…"

Roy’s face burned crimson as he pulled a small package from behind his back.

"A gift. From my hometown."

"Maybe… it’ll help Sister sleep well for once~"

The sunset had faded.

But the boy’s gentle, earnest smile before her…

Shone so brightly, Elsa wanted to cry.
