"Fan N Star," a website that delivers idol ranking information, opened birthday support for the group BTS Jungkook on July 23rd of last month.

The success of Jungkook's birthday project will be confirmed by the number of rainbow stars (points collected on the site) donated by domestic fans. The more stars gather the more celebratory ads are posted in various places.

The way to participate in the event is simple. It is a way of donating to advertising products that fans want to collect hard-earned stars. The number of donations is unlimited and another product can be added.

Currently, 154,409 stars are gathered in Jungkook's birthday support. The CM board of Hapjeong Station, Myeong-dong Media Facade, and Japanese electronic display boards have been achieved. The comments are flooded with congratulatory messages from domestic and international fans, including "I love you so much" and "Happy birthday Jungkook."
