'Fan N Star' is working on a birthday project for the NCT Mark.

‘Fan N Star’, a place where fans and stars become one, has started a surprise event for Mark last July 18. It is a global fan-heart project where advertisements in celebration of his birthday are displayed in various places.

Mark's birthday project will be held simultaneously by 'Fan N Star' in Korea, China, Japan, English, and Vietnam. The project's success will depend on the number of rainbow stars (points collected on the site) donated by domestic and foreign fans.

Participation in the event is through the "ADs." section on the 'Fan N Star' website. It is a method of donating the stars that fans have collected to donate to advertising products of their choice. You can gather stars by performing various activities on the site or completing various missions.
