The number of rainbow stars (points that
can be collected on the website) donated by fans determines the success of her
birthday project. The more stars you collected, the more congratulatory ads are
posted in various places.
When 20,000 stars were gathered, a congratulatory video was shown on the CM board (square column) at Hapjeong Station, Seoul Subway. When reaching 55,000 stars, a congratulatory video will also appear on the electronic board of Shinjuku Shin-Okubo, Tokyo, Japan. In addition, gifts such as Jamsil large digital signs, Hongdae M screens, and Seoul bus advertisements are waiting for fans.
