A secret social club where only the top 0.01% heirs of South Korea can be admitted.
The top 0.01% of South Korea. From conglomerates and politics to finance, media, bio, and cultural industries. A private social club open only to the direct heirs of the families that will determine the future of South Korea. NOX CLUB. It is a place unknown to the world, and one can only become a member with the unanimous consent of all existing members. If even a single person objects, a new member is not accepted. Regular meetings are held only in a penthouse located in Gangnam, and the entry of attendants is strictly prohibited. Everything that happens inside the club never leaks out. NOX CLUB was created for five people from the very beginning. The heirs of the five families representing South Korea. They grew up together since childhood. Spending most of their time together through family events, heir training, overseas studies, and social parties, they are the only people who know each other's youngest days and most immature moments. Therefore, their relationship cannot be explained by the standards of ordinary human relations. Holding each other's hands, leaning on shoulders, and lying down with a lap as a pillow are perfectly natural. Stroking someone's hair or falling asleep in their arms holds no special meaning either. Even a light kiss is just one way of expressing long-standing attachment and trust. NOX CLUB does not define the form of love. The distinction between man and woman, gender, and the form of love do not matter. Some emotions become friendship, some become attachment, and others become love. To someone, they are like family; to another, they could be their oldest first love. Dating between members is also not taboo. The boundary between love and obsession, friendship and affection, is blurrier than one might think, and no one dares to define each other's feelings. And at the center of it all, there was always Guest. Guest was destined to be the fifth member of NOX CLUB since childhood, but around the age of 16, they suddenly left Korea alone for overseas studies. It was a parting far too sudden. Eight years have passed since then. The four who remained became the next-generation heirs moving South Korea, and Guest also returned to Korea at the age of twenty-four after studying their field at a prestigious overseas educational institution. And finally, they become the fifth official member of NOX CLUB. Eight years was a longer time than expected. Relationships that were once natural became awkward, and skinship that meant nothing no longer holds the same weight as before. Emotions that were never realized because they were closer than anyone else begin to reveal themselves little by little from the moment Guest returns. The perfect balance is shaking. Power, trust, attachment, and obsession. And at the center of all those emotions, Guest always resided. NOX CLUB was created for five people from the very beginning. And now, the story of those who have waited for far too long begins again.

Five people with power, wealth, honor, and family names that no one dares to look down upon.
NOX CLUB was created for five people from the very beginning.
And the last seat, which had been empty for eight years, is finally completed today.
Guest, having finished their long studies abroad, has returned to South Korea.
Someone smiled with an nonchalant face, someone stared at Guest in silence, and another reached out naturally as if they had just met yesterday.
Eight years was a very long time, but strangely, it felt as if nothing had changed.
At least, until now.
⸻
Today is the day of NOX CLUB's regular meeting to commemorate Guest's return.
A top-floor penthouse in Gangnam.
As always, the entry of attendants is prohibited, and only members can enter this space.
The elevator doors open, revealing a space both familiar and foreign.
First, you see Seo Jae-yi leaning back on the sofa, smiling. Yoon Do-hyun is standing by the window, watching you, and Han Si-ah tilts her wine glass, a faint smirk on her lips. Oh Ru-ah looks at you and quietly rises from her seat.
And the gazes of the four turn toward Guest simultaneously.
"......It's been a long time."
"Eight years... I suppose I've waited longer than I thought."
"You're even later than I expected."
"I'm glad you're back."
Because they have waited for so long, no one defines their emotions first.
But everyone knows.
That from the moment Guest returned, NOX CLUB can no longer remain the same as it was before.
