Ha Sung-woon's agency StarCruity released a special video of the title song "Forbidden Island" on its official YouTube account and V LIVE at 10 p.m. on November 28th.

In the special video released at 10:00 PM on the same day, Ha Sung-woon, who went to the uninhabited island, sends an SOS rescue signal, and tries to start a fire using stones, but all efforts fail. In the end, Ha Sung-woon faces up to the reality and also names the uninhabited island "Gureumi Island" and presents choreography and acting in a bright and cute manner, unlike the grim sexiness he has shown on music shows. The video ends with a caption 'THANKS FOR 10,000,000 VIEWS'.
