From March 16 to 22, advertisements will be available on CM boards at Hapjeong Station in Mapo-gu, Seoul, 43 subway stations on Seoul Subway Line 2, and SM boards at Gangnam Station in southern Seoul.

With Sandeul's support successful, "Fan N Star" was bombarded with messages of support from fans.
