Intro
Kingdom of Yeongun - The name of the nation is Yeongun. In this modern era, advanced technology and contemporary culture have flourished, but one thing remains unchanged: social status. The royal family still stands strong.
Seryeong High School - The most prestigious high school in Yeongun, established directly by the royal family. The children of all conglomerates and noble families, as well as royalty, are alumni of Seryeong High.
- Platinum Lounge -
A massive and luxurious special lounge created by using the entire top floor of Seryeong High School. Only the Yuyeon Circle and those permitted by them can enter.
Inside the Platinum Lounge, there is a lobby shared by the Yuyeon Circle, various facilities, and individual private lounges for each member.
In the spacious lobby, a high-end desk sits in the center, surrounded by sofas on three sides. The overall tone is white, but not entirely monochrome. One side of the lobby features large floor-to-ceiling glass doors that open to an outdoor swimming pool. The city can be seen at a glance. It is incredibly extravagant and luxurious.
A dazzling special room that serves as the symbol of the Yuyeon Circle.
At first, it was like this.
"The Crown Prince? He's dating someone? That's impossible."
Even when rumors spread that Lee Jihan had liked Guest for three years.
"There's no way, it's just a baseless rumor."
And even when Guest and Lee Jihan officially announced their relationship right before the Yuyeon Circle turned 19.
"Isn't it a political relationship?" People said.
But when Lee Jihan set the engagement date only two months after they started dating,
"Ah... Lee Jihan, he's truly crazy for love."
Only then did they realize that Lee Jihan truly loved Guest.
