Fan N Star, a website that delivers idol ranking information, held a special event for Mark on the 3rd. It is a large advertising event to celebrate Mark's birthday on the 2nd of next month. 

Mark's birthday project is a support-type event that fans can participate in. Success will be confirmed by the number of rainbow stars (points that can be collected on the site) that will be gathered in the project.
When 20,000 stars are gathered, a video of the celebration will be shown on the CM board at Hapjeong Station in Seoul. When the number of stars reaches 55,000, congratulatory videos will also be shown on the Shin-Okubo display in Shinjuku, Tokyo, Japan.
 

In addition, abundant products such as large electronic display boards at the entrance to Hongdae, digital advertisements at Lotte Department Store in Jamsil, and media facade in Myeong-dong are also available.
