Summary
There is a level of unpredictability that Han Yoohyun expects when it comes to his hyung.
Where he goes. Who he runs into.
What item or beast he returns with.
What new odd idea he comes up with.
Where he draws the line between them.
It gives Yoohyun a strange sort of comfort, seeing his hyung stir up chaos around Guild Haeyeon at large. It is a brand of turbulence that he has come to appreciate, especially after the years apart— a self-inflicted wound to try and protect him.
Until his hyung suddenly starts avoiding him.
And that is unacceptable.
Han Yoojin has a realization and is torn between what should be and what he truly wants.

Summary
"Leader-nim, Han Yoojin-ssi has awakened."
Han Yoohyun has never hidden his hyung's presence but has never drawn attention to him either, all for the sake of keeping his precious hyung safe. He pushes back against his racing heart, furrows his eyebrows, and crosses his arms.
"Of course my hyung has awakened. What does that matter now?"
"Reawakened. Han Yoojin-ssi has reawakened."
It is as if time stops in that very moment.
Yoohyun's brain slows to a crawl as those words cycle on repeat.
His hyung. Reawaken. His hyung. Reawaken.
For a moment, he imagines a world where his hyung reawakens to become S+ grade like himself— and oh, what a perfect future that would be. Unfortunately, reawakening is a rare and the few times it happens, it only elevates the superpower user by one level.
Except, against all odds, his beloved hyung soon reads as an S+ grade guide.
And this is the day his heart restarts. It is the day their paired lives are reborn.
Han Yoohyun awakens as an S+ grade esper and intends to keep his hyung by his side.

Summary
Bright red frills define one of Han Yoohyun's most vivid childhood memories.
It is just another day of her parents pretending like they are a normal family as they dress up and head out to some overly fancy event. It is easier to go along with the flow of things so that the farce of them being a happy family ends sooner.
However, it isn't her own dress that she recalls so clearly.
No, it is her older sister's matching outfit that stands out.
At first, she doesn't understand why the other girls at school want to be princesses, wearing pretty dresses and dancing as they wait for their handsome prince to arrive. But when Yoojin takes her hand and leads her away from their parents and into a dance, her bright expression full of smiles and encouragement and her lacy red dress accentuating her energy and enthusiasm, she finally understands.
Yoojin is the princess her classmates speak of.
And Yoohyun wonders who she is waiting for.
Han Yoohyun aspires to become her unnie's shining prince.

Summary
When Han Yoohyun was smaller many years ago, his beloved hyung was like a gentle giant, keeping watching over him. It is only now, when he has all this power in hand, that he realizes just how small his older brother really is… and more than a small part of him revels in that difference.
Part of that satisfaction is pure. It is a satisfaction in being able to provide for and protect his beloved brother in the way that was once afforded to him.
Being tall enough to reach things that are higher—
Being strong enough to open and carry various objects—
Being forceful enough to stop randoms from harassing him—
It is deeply satisfying.
But the other part is darker.
That part wants his hyung all to himself— to look at only him, to talk to only him, to engage only with him. With their physical relationship being what it is, he quickly succumbs to his deepest instincts.
Yoojin seems more than happy to let him have his way, so Yoohyun continues on.
Han Yoojin wonders when his brother grew to be so big. Han Yoohyun wonders when his hyung will notice his feelings.

Summary
“Shut your mouth before I shut it for you.”
What.
What did he just say?
Yoojin looks up and takes in his dongsaeng’s face properly. His expression is blank and his handsome face is stiff with tension, but his gaze tells a different story.
It’s not that Yoojin does not understand his younger brother’s anger and worry. He disappeared all of a sudden, then reappeared out of nowhere. And strictly speaking, it isn’t the first time Yoojin was suddenly spirited somewhere else without warning.
But Yoohyun has never been so quick to dismiss his words.
Even before, during more turbulent events like his… yes, kidnapping at the hands of the MKC Guild’s offshoots, his dongsaeng at least heard him and his thoughts out, and eventually went along with whatever Yoojin told him. He really is a good guy.
Yoojin finds himself at a loss, but knows he must persist.
“Yoohyun-ah, I—”
Right then, the wind brushes his cheeks and Han Yoohyun follows through.
Han Yoojin disappears in a dungeon and Han Yoohyun decides that this is the last time he will ever do so.

Summary
"Hyung, it has been a while."
It is impossible to mistake this voice.
It is a voice he knows intimately in all shades.
All of his thoughts dissipate into this crimson space.
On instinct, Han Yoojin closes the gap and throws his arms around the figure standing before the flames. He does not need to see to know that it is him— his precious, beloved brother.
This person whose life slipped through his fingers.
This person without whom, Han Yoojin is nothing.
Between the buzzing energy of the blood moon, this deep crimson space infused with sensual spice, the crackling flames, and his heart beating ever faster with guilt and desire, with duties and dreams long held, Han Yoojin allows himself this one moment.
In this world with just the two of them, surely he can be forgiven.
It takes a moment for Han Yoojin to register the press of cool lips against his throat, but when twin points pierce his skin, a deep sigh escapes his lips and he sinks into the depths.
Han Yoojin uses his wish stone and is taken in by the eternal night.

Summary
When Han Yoohyun first Awakens as an S-class hunter, a newfound realization about his strange, hard to define feelings towards his precious older brother strikes him. He wonders if perhaps, his hyung is aware of what his heart truly feels and if this is why he kept his distance from him all along.
Though if that is the case, it begs the question— why did his hyung's heart change so suddenly?
Because one moment, his hyung is being so stubborn, insisting on going along with those Awakening 'brokers' despite Han Yoohyun repeatedly warning him otherwise.
Then just minutes later, he returns to the guest suite where his hyung is staying, his hyung looks him over in a peculiar way, and immediately lunges forward to hug him.
It catches him off guard, but returning his embrace is never in question.
After all, Han Yoohyun would do anything for him.
Merely having him back is more than enough.
…until now, at least.
Something is different and he can't quite figure out what it is.
Han Yoohyun notices something is strange as of late and works with Bak Yerim to figure out what it is.

Summary
"What do you want from me, hyung?"
He wants to be around his Yoohyun-ie.
Even after telling him to keep his distance.
"I-I… I… um…"
He does not recall what brought him to his brother's office.
However, the past few months have made a few things clear.
For one, he is addicted to his brother's scent. There is no hiding it anymore.
There is something about his brand of bold, rich spice and deep smoky vibes that simultaneously puts him at ease and makes his heart race and crave more. Even if he doesn't know everything about how secondary dynamics work, he knows that this feeling is so similar to that particular day back then.
It is an ardent, sensual desire that constantly craves more.
As for his brother, Han Yoohyun has gone well out of his way to make his intentions obvious. Hell, there is no way Yoojin can pretend it is anything else—not after feeling that passion firsthand.
It is impossible for him to ignore what he has always wanted.
Han Yoojin regresses to a new world, reunites with his brother, and has certain realizations.
