Fan & Star is hosting a birthday ad event for trot singer Kim Joong-Yeon.

Fan & Star, a place where fans and stars come together as one, held a surprise project for Kim Joong-Yeon on the 11th. It is a large advertising event where videos celebrating his birthday are posted in various places.

Kim Joong-Yeon's birthday event is determined by the number of rainbow stars (points that can be collected on the site) donated by fans. When more than 20,000 stars are gathered, congratulatory advertisements are posted.

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. The number of donations is unlimited and another product can be added.
