The enormous mansion is divided into two wings; the east building is for the master of the house, which means this division is for Jae Ha, Tsuyu, and Jihun. And, the west side is for the children. In this case, the one resided here is Ryan, the child of wedlock, and the twin. Ryan didn't care since he prefers to stay at this wing with the lovely twin rather than meeting an annoying person every day before going to sleep.
With the total three levels, the two wings are connected by a single, long hallway. The highest level is exceptionally for educational and work-related purposes only, such as the library and office. While the rest are left unused. The middle one consists of bedrooms and guest rooms. And the ground floor is the living room, kitchen, gym, and other necessities.
