“Sure, I’ll get going.”

Moving to the exit, he waves.

“See you later then.”

“Likewise, dear Captain.”

The moment he’s a good distance away, the woman snaps her finger and the sound echoes throughout the empty library.

“Coast clear.”

And from a corner close by, a girl of green hair with glasses peeks out.

The Assistant Alchemist, Sucrose.

“Th- Thank you, this… this should be sufficient.”

Humming, Lisa nods with a smile.

“Yes, dear, it should be.”

What a day it is today.

It doesn’t take long for the man to spot their Outrider at the entrance of their Headquarters, alongside the Honorary Knight.

“Yo.”

Grinning slightly, he raises his hand in greeting.

“What’s up?”

“There you are!”

Amber waves in response, while the Traveler by her side wordlessly nods in acknowledgement.

“We spotted something in Windrise today!”

“Oh? Is that so?”

The tanned man hums, folding his arms.

“Do tell me about it.”

After a while of explaining, he decides to join the duo in taking a look at the odd “thing” they saw by the Statue of The Seven’s side.

A doll-like creature, small and has the ability to levitate.

It’s nothing like what they’ve ever seen before.

To make it more complicated, said creature also seems to have a will of its own and constantly dodges their attempts on getting a hold of it.

Their little game of chase goes on until dusk, only then did they lose track of the poor thing and decide to return to the Headquarters.

Throughout the duration of it, however, the man has to admit that it’s rather entertaining.

And nostalgic, since he used to play that kind of game with…

`“Catch me if you can!”

“Challenge accepted!”`

The sound of their laughter in those distant days still ring clearly in his ears, echoes of a pleasant childhood he knows he doesn’t deserve.

“Sheesh, it was so fast.”

Amber huffs on their way back.

“And small too, which makes grabbing it all the more difficult.”

“You can’t blame it, really.”

Paimon, the Honorary Knight’s floating companion, comments.

“When some strangers just suddenly show up and try to get a hold of you, of course you run.”

“That’s right.”

Kaeya hums, holding his chin in thought.

“Besides, I’m sure I at least managed to tell what kind of thing it was.”

At this, the brunette turns to him immediately.

“You did? That’s fast!”

“Of course.”

Smirking, he continues.

“It’s an elemental being, a wisp amongst Mondstadt’s thousand winds.”

And once again, a remark catches him off-guard.

“You’re amazing, Sir Kaeya!”

The Outrider did not just-

“I’m glad we have you within the Knights’ ranks!”

Oh Barbatos, his face must have looked so ridiculous that it caused both Amber herself and the Traveler to stare when they finally took notice of it.

“Kaeya?”

Paimon waves a hand in front of his eyes.

“Helloooo?”

Maybe his smile literally froze on his face, though.

“He’s acting weird…”

Amber mumbles.

“Well, at least we’re here now.”

Indeed, they’re currently standing just before the entrance of the Knights of Favonius’ Headquarters.

The sky, painted in fiery orange of the setting sun, reminds the man of someone’s eyes.

Orbs that shine with burning passion, an unrelenting desire to protect this land with everything this person has.

A tug on his sleeve brings him back to reality, looking to the side to find their Honorary Knight smiling up at him.

The third thing is…

Why is everyone suddenly so hard to read?

From the ones he met early morning to those he met in the late afternoon, they’re all so…

Unpredictable.

And Amber beams at him, taking his right hand as the Traveler had his left.

Then they lead him inside together.

His heart skips a beat once the large doors open, revealing the rest of Ordo Favonius along with colorful decorations.

As well as a gigantic “Happy Birthday” hanging from the ceiling.

“Happy birthday, big bro Kaeya!!”

Klee comes jumping down from a hovering flower - Albedo’s, he notes - and throws various cute-looking things, which he’s sure are explosives.

Although when they do blow up, it’s all confetti and glitter.

So this is why Jean agreed…

The two by his sides quickly let go of his hands as the small girl falls right into his arms, giggling.

“Yay!! The new formula worked!”

“Splendidly.”

Lisa chuckles, snapping her fingers and the lights go out.

“Time for the cake.”

At this, he sees a cart being pushed out by Noelle and candles illuminate the area.

On it lays a cake of three layers, each of a different color.

Ocean blue, ice blue and white, from top to bottom.

“Please make a wish, Sir Kaeya.”

Along with the maid’s smile, he makes out everyone else’s in the dimly lit lobby.

Ah… a birthday wish.

Smiling back at them, he nods.

But what should he wish for, really?

They went through the trouble to organize a party for him right under his nose and it is rather impressive how they’ve managed, if he were to be honest.

He knows the birth date is always on one’s profile when they apply for a job, but he didn’t expect them to pay that any mind.

Especially when it’s his.

He hadn’t celebrated it in years, after that event took place.

…

He would be lying if he said there was nothing he wanted to wish for, though.

`“Happy birthday!”`

The image of a young boy, smiling brightly as he handed Kaeya a gift.

That had been the first time someone threw a birthday party for him.

Chuckling, the tanned man moves to blow the candles as his wish comes to mind.

A childish dream he still believed in.

The girl in his arms cheer when everybody’s applause resounds, light flickering back on with another snap of the librarian’s fingers.

“On behalf of every knight within Ordo Favonius, I thank you for your contribution in maintaining the peace of our city.”

Jean steps forward, a hand on her heart as she speaks.

“We hope that you enjoy your time here, as well as allowing this place to become your second home.”

The warmth in his chest intensifies, a feeling he hadn’t felt for so long.

And the woman smiles.

“Everyone, let us say it together.”

From the shy Assistant Alchemist to the outgoing Outrider, from the strict Acting Grand Master to the friendly Honorary Knight, from the rarely seen Chief Alchemist to the ever-present Apprentice Knight, from the graceful Librarian to the explosive Spark Knight.

All of them, with bright smiles, go on and-

“Happy birthday, Kaeya!”

Even if his eyes feel a bit like burning right now, the man grins back at them.

“Thank you, all of you.”

He doesn’t think he deserves it.

Yet as he feels their sincere affection and gratitude, he can’t push them away.

Perhaps… for this occasion, he’ll allow himself to be honest once more.

When stars fill the night sky and the moon ascends to its peak, the Cavalry Captain leans onto the railing of the small balcony as the party goes on inside the building.

He wonders if… it could have been this way, if none of the horrible events a few years back happened.

Other than throwing a party for him, Sucrose gave him quite a pleasant surprise by being able to make untesils somewhat “alive”. Perhaps that was why she needed them this morning, so they could easily move around for everyone to use.

The girl’s bio-alchemy skills are getting better and better, as expected of someone working alongside Mondstadt’s best alchemist.

Well, she had potential anyway.

That said-

“… Having some time to yourself?”

He pauses upon hearing the voice.

This can’t be-

“That is to be expected, you’ve never been a big fan of parties despite your eccentric nature.”

Whipping his head to the source of the voice, he finds a familiar redhead sitting on the railing to the side - a leg on it and one dangling - away from people’s view, in a black cloak he hadn’t seen for so long.

“You…”

His voice comes out barely audible, like a faint whisper of utter disbelief.

“Why…”

“I want nothing to do with the Knights of Favonius.”

The other sighs, glancing at him.

“But since it is a special day, I’ll make an exception.”

At that, the tanned man goes silent.

An exception? For…

“Before you even get to that, stop.”

Currently masked, the redhead only waves him over.

“Come here.”

That mask is different, not the same one he used before.

Considering what it was for, it isn’t hard to understand why the other abandoned it along with “that”.

Confused but curious, he does as he was told and stops in his tracks upon seeing the offered hand.

“… Diluc?”

At the mention of his name, the other averts his gaze.

“Hurry, we don’t have all night.”

Smirking, Kaeya finally takes the hand and chuckles quietly.

“Where are you taking me, O Nocturnal Guardian of Mondstadt?”

“… You’ll see soon enough.”

In quick succession, the redhead pulls the man closer to himself and sweeps him off of his feet using his leg.

The smirk on the Cavalry Captain’s face immediately gets replaced by a look of surprise due to the sudden bridal carry and in turn, the Darknight Hero’s lips quirk up slightly.

“Mond’s Knight of Ice.”
