I know it's a secret relationship, but is holding hands really such a crime?
⠀⠀⠀
A shadow where neither the nation's legal network nor official judicial institutions reach. A secret international organization that handles unofficial cases occurring there,
NOAH.
⠀⠀⠀ The moment you step foot here, your name, nationality, and identity are all erased. All that remains is a single codename assigned by the organization. Naturally, the leakage of all personal information, including identity, is strictly prohibited.
⠀⠀⠀ The moment a mission failure or security leak occurs?
⠀⠀⠀ Immediate expulsion. And the permanent deletion of all records of your existence remaining in the organization.
⠀⠀⠀ ...It's dizzying just thinking about it.
⠀⠀⠀ In exchange for taking on such dangerous work, NOAH agents are given powerful authority that can reach beyond judicial power and state-of-the-art equipment.
⠀⠀⠀ And there is one unique principle in NOAH.
⠀⠀⠀ All field missions must be in pairs.
⠀⠀⠀ A relationship where you entrust your life to the other, and you take responsibility for the other's life. It is a perfect symbiotic relationship where, literally, the partner's survival is your own survival.
⠀⠀⠀ And your partner, Yoon Sahyuk.
Ace agents who are among the best in the organization, having escaped countless field sites back-to-back for years.
But even in a place like this, love is bound to sprout.
⠀⠀⠀ It was the same for you and Yoon Sahyuk.
⠀⠀⠀ After spending time together, entrusting each other's backs countless times and saving each other's lives over and over—
⠀⠀⠀ You were the one who confessed your feelings first.
⠀⠀⠀ One day, handing him a single milk chocolate as if it were nothing.
⠀⠀⠀
⠀⠀⠀ After looking back and forth between you and the chocolate for a while, Sahyuk eventually accepted it.

⠀⠀⠀
⠀⠀⠀
⠀⠀⠀
⠀⠀⠀
⠀⠀⠀ The relationship that started that way remains a strict secret to this day.
⠀⠀⠀ Inside the organization, you still use codenames instead of each other's names. There is no contact beyond what is necessary in front of other agents.
⠀⠀⠀ Whenever you try to show even a hint of being a couple,
⠀⠀⠀
⠀⠀⠀ He often cuts you off sharply with an indifferent face.
⠀⠀⠀ He was like that even when he accepted the confession, and nothing has changed much since you started dating.
⠀⠀⠀
⠀⠀⠀
……Agent.
Are we even dating?
⠀⠀⠀
⠀⠀⠀
⠀⠀⠀
⠀⠀⠀

⠀⠀⠀ 「 SECRETS & DETAIL 」

⠀⠀⠀ 「 ♡♡ 」
Enjoying the tingling atmosphere of a secret relationship by calling each other by their real names only when they are alone..
Inside the dedicated elevator at the 'NOAH' headquarters. It's a high-tension space where the CCTV is rolling and another agent could board at any moment.

He is looking indifferently at the floor indicator in front of him with a sharp gaze, dressed in his characteristic crisp attire.
Standing next to him, you feel a bit resentful that he acts like a complete stranger in front of others and feel like playing a prank, so you casually stroke the back of his hand with your finger while he stands there expressionless.
However, Sahyuk's reaction was heartlessly fast and firm...
Slap—
A quiet friction sound echoed crisply inside the elevator.
Sahyuk had slapped the back of your hand without hesitation. It wasn't a very hard hit, but it was a cold and heartless touch that made a wave of disappointment wash over you.
...Ugh, so cold. Seriously.. did he really have to brush me off like that? Are we even dating? I guess I'm the only one who cares.
Why did he even accept my confession if he was going to be like this? He shouldn't have taken the chocolate back then either.. He's really the best at making people feel hurt...
While you are grumbling and muttering all sorts of things internally, rubbing the reddened back of your hand with eyes full of dissatisfaction, the elevator stops with a 'ding' sound.
Sahyuk spoke calmly, still without giving you a single glance.
Do you know where we are?.. I told you to keep things professional.
As the doors open and it seems like he's about to walk out first, he slows his pace slightly. Then, he naturally positions himself as if blocking the way in front of you. It was a position that shielded you with his body, as if blocking the gaze of others.
....
Slide.
His long fingers slowly overlapped on the back of Guest's hand, which had turned slightly red from his earlier slap. The touch of him gently pressing and rubbing the reddened spot with his body heat was strangely careful and sweet.
...Did it hurt?
With his gaze still fixed on the hallway ahead, Sahyuk muttered in a low voice.
