Idol weekly ranking website "Fan N Star" released a birthday video of "W Project 4" Hwangyunseong.

On Oct. 30, "Fan N Star" released a video of Hwangyunseong, which is being screened at the Lotte Cinema theater in Nonhyeon-dong, southern Seoul. On October 4, "Fan & Star" opened Hwang Yoon-sung's event and achieved an electronic billboard ad.

This confirmed the CM board ads at Hapjeong Station in Mapo-gu, Seoul, SMboard ads at Gangnam Station in southern Seoul, electronic billboards at 43 stations on subway line 2 and the screen ads at Lotte Cinema's Shinto shrine from Oct. 22 to Oct. 28.

Hwangyunseong's support was successful, and fans' messages of support poured into "Fan N Star." Fans wrote in the comments, "Happy 20th birthday to Yoon-sung," and "I need something to say. I love you, Yoon-sung," and "I hope it's happy 1030 days."

Meanwhile, "Fan N Star" recently renewed its "Star Market" to "ADs." "Star Market" refers to idol support that was hosted by "Fan N Star." Previously, if "Fan N Star" randomly selected an artist and opened a support program, "ADs" is drawing attention as fans can open support for the idol group they support themselves.
