Fan & Star, a site that delivers idol ranking information, holds a special event for BTS J-hope on December 10th. It is an advertising project for j-hope, who will celebrate his birthday on February 18th next year.

J-Hope's birthday celebration event will be held simultaneously at the "Fan & Star" service in Korea, China, Japan, and English. The success will be confirmed by the number of rainbow-specific (points that can be collected on the site) donated by domestic and foreign fans.

The way to participate in the project is simple. It is a method of donating stars that fans have collected hard to advertise. The number of donations is unlimited, and other products can be added.
