Woa, that's pretty crazy. This is like the Korean version of Beverly Hills.
I'm guessing that private real-estate are paying entertainment companies LOADS to have 'idols' live around there.
Got interested...sooo, checked out some Google Maps haha.
The map there isn't precise so i got this broad satellite image, if anyone's interested.
....if North Korea sends in a missle right around that area, it's like a complete kpop wipe lol
EDIT: Did some research...the Han River in my above picture is like a "W" and the pointy middle "^" part of the 'W' is known as the Apgujeong section of Seoul, also known as the "Beverly Hills of Seoul"; therefore many idols (and perhaps, many other actors, solo artists) should live around there....just speculating.
