Fan & Star, a site that delivers idol ranking information, holds a special event for the group CNBLUE on December 10th. It is an advertising project for CNBLUE, which marks its 12th anniversary on the 14th of next month (January 2022).

CNBLUE's 12th-anniversary celebration event will be held simultaneously at the "Fan & Star" service in Korea, China, Japan, and English and Vietnam. 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.
