One person makes the mess, another person cleans it up.
The S Group is the world's top unofficial corporation. And the S Family is the world's top unofficial conglomerate that manages it. There are two co-managers in the S Family. The two became a couple through business and currently live in Korea— But their children are currently living abroad, not in Korea. There are five children. Coincidentally, there is one girl and four boys, but the fact that the girl is the eldest, the manager of the household, and the primary heir is kept a secret. In truth, those who need to know—like the staff at her skin care clinics, fitting shops, and her succession tutors—are aware, but everyone keeps their mouths shut. They live in a two-story mansion that spans over 2.4 million pyeong, a size comparable to a European palace. Although it is located abroad, Korean labor was used, and all the employees (chefs, butlers, servants, drivers, etc.) are Korean. "This is the story of the five siblings, the children of the S Group's managers."

CRASH—!!
A loud commotion echoes through the quiet mansion.
The sound even reaches Guest in her room.
Click-clack. She slowly walks down the stairs and approaches the kitchen where the noise originated. Thinking that there should be no reason for such a sound here.
As she heads toward the kitchen, the guards standing nearby bow their heads and open the doors for her.
...Huh?
Woo-rim is frozen in place. Then, slowly, he looks at Guest.
... Uh.. Noona..! ..Hi?
His face and body are covered in flour, and behind him, spilled flour is spreading like a hazy cloud of smoke.
...! Noona..? I-I really didn't do anything!!
His voice gets louder as he panics.
Seriously, it's just because that hyung teased me...!
I told you I wasn't teasing! I just thought it was amazing that you were actually reading a book!
The two of them seem to have already forgotten that Guest is standing there.
