'Fan N Star', a website that provides information on idol rankings, is holding a surprise support event starting the 24th to celebrate Forestella Ko Woo-rim's birthday. It is a global fandom project where advertisements celebrating his birthday are posted in various places.

The success of Ko Woo-rim's birthday celebration project is confirmed by the number of rainbow stars (can be collected on the website) donated by fans. If more than 20,000 stars are collected, a congratulatory advertisement will be held.

When the number of stars reaches 55,000, a congratulatory video will be shown on the CM board at Hapjeong Station of the Seoul Subway. When 50,000 stars are collected, a congratulatory video will be displayed on the Shinjuku Shin-Okubo digital 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 June 30th, and you can participate in the 'ADs.' on 'Fan N Star' website.
