The idol weekly ranking site "Fan & Star" has been holding a surprise support event for SEVENTEEN's Jeonghan since August 31st of last month. It is a global fan-heart project where advertisements to celebrate his birthday are posted in various places.

Jeonghan's birthday project will be successful with the number of rainbow stars (points that can be collected on the site) donated by fans. If more than 20,000 stars are gathered, a celebratory advertisement will be held.

When it reaches 20,000 stars, a congratulatory video will be shown on the CM board of Hapjeong Station in Seoul Subway. When 55,000 stars are gathered, a congratulatory video will also be uploaded on Shinjuku Shinokubo's electronic display board in Tokyo, Japan. In addition, there are also super-exclusive gifts such as M-screen in Hongdae, a large digital display board in Jamsil, and advertisements for Seoul buses.
