Just like Google Maps, Daum Maps offers street view on the streets. While not exactly an Easter egg that Daum put in the street view themselves, a fan who was going through the streets near Cube Entertainment found a pleasant surprise when they caught an idol going to work to the building.
The idol is none other than BTOB's Changsub, and he looks like he's intercomming himself into the company building. Changsub was just today asked if he knew that he was on the street view going into Cube Entertainment, and he responded, "This is my first time seeing this! It kind of makes me feel good."
