The idol weekly ranking site "Fan & Star" has been holding a surprise support event for the joy of Fly to the Sky since November 12th. It's a global fan project where advertisements to celebrate his birthday will post in various places.

The success of Hwan-hee's birthday project will be confirmed by the number of rainbow stars (points can collect on the site) donated by fans. When more than 20,000 stars gather, congratulatory advertisements will be held.

When the number of stars reaches 20,000, a congratulatory video will be screened on the CM board at Hapjeong Station on the Seoul Subway. When 55,000 stars gather, a congratulatory video will also be released on the Shinokubo electronic display in Shinjuku, Tokyo, Japan. In addition, ultra-high-end gifts such as Hongdae M Screen, Jamsil large digital electronic display, and Seoul bus advertisements are prepared.
