When 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 prepared.

The event will continue until April 7th, and you can participate in the 'ADs.' of the 'Fan N Star' website.
