"Fan & Star" released a video of Siwon on April 7, which is being screened at the CM Board at Hapjeong Station in Mapo-gu, Seoul. Earlier on March 13, "Fan & Star" opened a cool event and achieved an electronic billboard advertisement. As a result, advertisements will be made on the CM Board at Hapjeong Station in Mapo-gu, Seoul, from April 6 to April 12.

Siwon's support was successful, and "Fan & Star" was bombarded with messages of support from fans. Fans said in the comments, "E.L.F. congratulates you," "I miss you."

In "Fan & Star," fans can open their own electronic display support for artists they want. If you can make your own electronic display video, you can apply for "Special ADs" and "Global ADs" if you can't produce the video.
