Fan & Star, a website that delivers idol ranking information, opened a surprise project for Taeyeon of the group Girls' Generation on the 18th. This is a big advertising event to support her who announced her comeback next month.

Taeyeon's comeback celebration event will be held in cooperation with fans and 'Fan & Star'. Success is confirmed by the number of rainbow stars (points that can be collected on the site) that gather in the project.

Participation in the event can be made at the As-Dot (ADs) section on the Fan & Star website. It is a method of donating stars that fans want to collect. Stars can be obtained by doing various activities on the site.
