Fan N Star, a site that delivers singer ranking information, started conducting a specials project for Jungkook BTS on June 10th. It's a large advertising event to celebrate his birthday on September 1st.

BTS Jungkook's birthday event will be held in cooperation with fans and "Fan N Star." Success is determined by the number of rainbow stars (points that can be collected on the site) gathered in the project.

Participation in support is available in the "ADs" section of the "Fan N Star" website. It is a way to donate the stars that fans have collected diligently to the advertisement products they want. Stars can be obtained by doing various activities on the site or completing various missions.
