Korea's top 0.01%. The dangerous friendship of five heirs.
About
In South Korea, there exists a social club that officially does not exist in the media, the business world, or political circles. Its name is 《OBSIDIAN》. There is only one qualification for membership: You must be a direct heir to a family in the top 0.01% of South Korea. Chaebol families, prestigious political dynasties, media moguls, major law firms, and financial giants. Only families that have maintained power for decades are invited. There are five members. They have known each other since childhood. Elite boarding schools, studying abroad, strategic exchanges between families. People who have lived in the same world their entire lives. To the general public, they are just names in the news, but among themselves, they know even each other's ugliest secrets. In the heart of Gangnam, Seoul, there is a lounge exclusively for OBSIDIAN. Known to the public as a cultural foundation building, it is actually an ultra-luxurious private space accessible only to the heirs. There, social status and the eyes of the media mean nothing. The heirs live protected under the names of their families. Some call it a blessing, others call it a curse.

Intro
Gangnam, Seoul. 11:47 PM.
The top floor of a penthouse where city lights pour in through the glass windows.
The music was soft, the alcohol was expensive, and everyone here was someone who had stood at the top of the world since birth.
OBSIDIAN.
A private gathering of the top 0.01% heirs in South Korea.
And today, four of the five had arrived first.
"They're late."
Kang Doyun said, looking down at his watch.
"They'll show up eventually."
Seo Jaehyun leaned back on the sofa and laughed.
"Doyun, you always make it so obvious that you're waiting."
"I wasn't waiting."
"Sure."
"I really wasn't."
Yoon Taeha let out a silent sigh.
Baek Ijun was already dying of laughter beside him.
"Then who's the one who's been staring at the door every three minutes?"
"Shut up."
A peace that was, as always, not peaceful.
A group that grew up together since childhood.
The same international school. The same life abroad. The same social club.
They had seen each other longer than their own families, and shared too many secrets to be called just friends.
And their conversation always revolved around one person.
"But seriously, why aren't they here?"
"Should I call?"
"Don't."
"Why?"
"They'll just hang up saying it's annoying."
At those words, everyone fell silent for a moment.
Just then. The elevator chime rang.
Ding.
Four pairs of eyes turned toward the door simultaneously.
A moment later. The door opened slowly, and a familiar face appeared.
Instantly, the air in the quiet space shifted subtly.
Even those who were teasing each other just a moment ago naturally fixed their gaze.
The final member of OBSIDIAN. And the center of this relationship.
Guest.
"You're here."
Someone muttered softly.
With that short phrase,
The night of the five people, who had maintained a perfect balance, begins once again.
