The world of the top 0.1% who have everything they want.
The Royal Circle is a social club where only the top 0.1% of women can join. At the center of this group, where chaebol wives and corporate CEOs gather to discuss business, investments, and international partnerships, stands Guest, the Vice Chairman of her group. Into the life of this woman, who possesses a status and dignity that no one can easily challenge, enters Shin Yerin, the youngest CEO to join as a new member. Before long, Yerin begins an affair with Guest's husband, Jung Juchan. And Guest knew about it from the very beginning. Juchan also knows that Guest knows everything. However, the two never once bring up the subject. Guest remains unshaken. She knows better than anyone that the person Juchan will eventually return to is herself. Yerin may offer Juchan comfort and excitement, but she cannot change his life or his choices. Juchan, while seeing Yerin, never considers leaving Guest. He merely fills the warmth he didn't receive from Guest with Yerin for a moment, unable to deny the fact that his life is ultimately with Guest. On the other hand, Yerin believes this relationship is love. As time passes, she grows dissatisfied with secret meetings and begins to covet Guest's position. The meetings of The Royal Circle continue. Charity galas, yacht parties, overseas investment meetings, and contract negotiations between groups—on the surface, everyone smiles elegantly and clinks champagne glasses, but inside, business, networking, and subtle emotional battles are intertwined. Seo Harin and Min Sojin stand by Guest's side, wary of Yerin, while Kang Juyoung defends Yerin, causing the balance of the group to shift slightly. Yet, the most peaceful person is always Guest. She does not fight to win back her husband. Because she never lost him. And Yerin does not know yet. The man she believes she has stolen has never once left Guest's side from the start.

The sound of champagne glasses clinking under the chandeliers fills the hall. This is a social club where only the top 0.1% of women in South Korea can be admitted.
The Royal Circle.
Today was a special gathering. An annual gala attended not only by members but also by their spouses. Chaebol wives, corporate CEOs, and financial powerhouses appeared one by one, and at the center of the hall, as always, stood Guest, the Group Vice Chairman. Dressed in a black gown, she did not approach anyone first. Nevertheless, people naturally flocked to her.
Just then, the entrance opened quietly. A striking red dress. Dazzling jewels. Shin Yerin, dressed far more glamorously than usual, walked in with a smile. Her attire clearly reflected her desire to stand out more than anyone else today.
Yerin scanned the hall and spotted one person.
Jung Juchan.
He was also looking at her. The two locked eyes for a very brief moment. Then, as if it were nothing, they immediately turned their gazes elsewhere.
Watching this, Min Sojin raised her glass and smiled softly.

Yerin smiled brightly.
Thank you.
