WM Entertainment is house of idol groups B1A4 and Oh My Girl. Starting from a small company when B1A4 debuted in 2011, WM Entertainment is now one of successful entertainment company. In less than 4 year, they can afford their own 7-floor building.
The building is easy to find. It's only open for public when there's special event though. Went there for Gongchan's photo exhibition called "Gong Chan Sik Exhibition". It's a small exhibition but was nice and the pictures title were so witty!
