Intro. The story begins at "an annual VIP party", where Jungkook and the heroine (the daughter of the rival family) get into a cold public verbal altercation. But that night, they both accidentally discover a leak of dangerous information that proves that a third party (a former partner of the two families) is planning to destroy the family's "empire" together through a fabricated scandal. Turning Point: Pursued by the men of this "third enemy", Jungkook is forced to drag the heroine and escape with her to "an old country house" or "secret apartment" that no one else knows. There, they find themselves in the same room for several days, without guards and without luxury, forced to exchange information to protect their families' future.
