[The Fact | Reporter Choi Joo-bin] “Happy birthday Siwon!”
Weekly idol ranking website 'Fan N Star' is holding a surprise support event starting on the 16th to celebrate Super Junior member Siwon's birthday. This is a global fandom project where ads celebrating his birthday are posted in various places.
The success of the Siwon birthday celebration project is confirmed by the number of rainbow stars (can be collected on the website) donated by fans. If more than 20,000 stars are collected, a congratulatory advertisement will be held.
When the number of stars reaches 50,000, a congratulatory video will be shown on the CM board at Hapjeong station of the Seoul Subway. Once 35,000 stars are collected, a congratulatory video will be displayed on the Shinjuku Shin-Okubo electronic display board in Tokyo, Japan. In addition, special gifts such as Hongdae M Screen, Jamsil large digital display board, and Seoul bus advertisement are also prepared.
The event will continue until March 24 and you can participate on the 'FannStar' website.
