Fan & Star, a website that delivers idol ranking information, launched a special event for the group Seventeen Wonwoo on the 11th of last month. It is a large advertising project to celebrate his birthday on the 17th of next month.

The way to participate in the project is simple. It is a method of donating rainbow stars (points that can be collected on the site) that fans have worked hard to collect to advertising products that they want. Stars can be obtained by doing various activities on the site or completing various missions.

Currently, Wonwoo's birthday support includes electronic boards at subway stations in Seoul, as well as super-high-end products such as the famous camera app Splash Banner, Hongdae M-Screen, Seoul Bus Advertising, and Japanese electronic boards.
