The upper stream of Hongjecheon has long history. This region has been called in different names in different eras. Those names have been made after the buildings in nearby areas, all of which now disappeared. Among the buildings, there was a dismantled building like the Shinyoung Shopping Complex there is an area now under restoration plan such as Baeksukdongcheon and an already-restored building like Segumjeong. Buildings are not the only objects of restoration. Hongjecheon was also restored a few years ago. The history of Segumjeong and Hongjecheon was also restored and perhaps everything the film shows may be a kind of restoration.
