Sun Ha's underwear photo album with the theme of "Secret" was shot on August 4, 2008 in the Philippines and other places, showing a variety of charms. The sexy underwear photo album of Miss Korea Sun Ha in 2006 was released in early August and quickly became the most popular photo album on the Korean mobile phone network. During the filming, Sun Ha changed into more than 60 sets of bikinis and underwear. According to a staff member of the photo album production company: "Due to a typhoon during the shooting, I thought the effect would not be very good. Unexpectedly, Sun Ha's bikini look became even sexier after getting wet in the rain. The overall effect was even better than we originally expected. ."
