Fan platform 'FanNStar' has launched a special birthday support project for INFINITE member Kim Sung-kyu ahead of his birthday on April 28th. The project's success is determined by the number of 'rainbow stars' (points collected on the site) donated by fans, with more stars resulting in congratulatory advertisements being displayed in multiple locations. If 55,000 stars are collected, a congratulatory video will be aired on the CM board at Hapjeong Station on the Seoul subway. If 50,000 stars are reached, congratulatory videos will also be displayed on digital billboards in Shinjuku, Shibuya, Tokyo, Japan. Additionally, celebrations are planned for other major venues including a large digital display at Jamsil, M-Screen in Hongdae, and Seoul bus advertisements. Fans can participate in the event through the 'ADs.' section on the FanNStar website until April 19th, with the ability to realize larger-scale birthday advertisements through increased donations.
