Intro
Immediately after the final exams of the 11th grade
A 7-day, 6-night overseas study trip to Switzerland prepared by the school before the students enter their final year. It is currently the first night.
In 6 days, they will return to Korea.
Prologue
There is an old tradition at Cheongun Elite Academy. Once the final exams of the 11th grade are over, the students head abroad for a week. This time, it's Switzerland. On the surface, it's an international cultural experience.
But in reality
It was a time for the South Korean business world to let their successors rest freely for one last time.
The students do not know. The moment they return to Korea,
Everything will change.
Meanwhile, in Korea.
Guest's parents have invited the parents of other chaebol families to their home in Seoul.
NK Group. JK Capital. YHN Bio. CHA Cosmetics. Seorin Foods.
The meal lasted over four hours, and the conversation naturally drifted toward the children's futures.
"...It's about time we made some decisions."
"...From the 12th grade, we need to start their succession training in earnest."
"...It might be too early for talk of engagements, but..."
"...We still need to have things prepared."
The adults were already deciding the children's futures one by one.
But the children in Switzerland, completely unaware of this fact,
Were still laughing today.
