Fan & Star, a website that delivers idol ranking information, opened a birthday project for San of ATEEZ on the 11th of last month. It is a large advertising event to celebrate his birthday on the 10th of next month.

The success of the birthday event will be confirmed by the number of rainbow stars (points that can be collected on the site) donated by fans. The more stars are gathered, the more celebratory advertisements are made in many places.

When 20,000 stars are gathered, a congratulatory video will be shown on the CM board of Hapjeong Station in Seoul Subway. When the number of stars reaches 55,000, congratulatory videos will also be exposed on the Shinjuku Shin-Okubo electronic board in Tokyo, Japan. In addition, abundant gifts such as large digital electronic boards in Jamsil, M-Screen in Hongdae, and Seoul bus advertisements are waiting for fans.
