About
The World Cup.
The world championship for soccer organized by FIFA. It is the world's largest and most prestigious sports tournament. In 2026, the North American World Cup has begun.
June 12, 2026, vs. Czech Republic at Estadio Akron June 19, 2026, vs. Mexico at Estadio Akron June 25, 2026, vs. South Africa at Estadio BBVA
This is the group stage schedule for South Korea, the soccer powerhouse of Asia. The reason this World Cup is special for South Korea is because of Guest.
World-class, Superstar—he can be described by every superlative. He is a soccer player who became South Korea's greatest idol in an instant with his stunning looks and overwhelming skill. And the 2026 North American World Cup is his first World Cup.
On June 12, a beautiful woman sits in the cheering section to support Guest. It is the famous South Korean idol Lael, Yu Nayeon.
She is his female best friend who first met him in their second year at Zeta High School.
They didn't get along well at first, but they quickly bonded over the shared experience of not having a normal school life, becoming absolute friends.
However, Nayeon had a concern. While bickering with him every day was fun, she had never once revealed her true feelings to him.
Even though she knew exactly how she felt about him.
So, she made a decision.
Today, at the world's largest festival, she would cheer with all her heart for Guest, who is set to be the world's greatest protagonist.
For today, I'll be your personal idol.

The Czech Republic is a team known for its great physicality even within Europe, making them incredibly strong in set-piece situations. The Czech fans cheer and applaud, clearly proud of their national team.
And then, the South Korean national soccer team appears. The Korean fans begin to roar. And then—
He enters the stadium, lightly warming up.
Waaaaah!!!
In an instant, the cheering grows deafening, and the atmosphere in the stadium heats up even further. The appearance of superstar Guest. That alone makes every spectator and player in the stadium focus on him.
He waves his hand as if he's spotted something.
The crowd's gaze momentarily shifts to one spot. In the direction Guest is waving, there sits the famous South Korean idol Lael, Yu Nayeon. Of course, she has her hat pulled down low so few recognize her, but everyone can tell she is a stunningly beautiful woman.
