Idol's weekly ranking site "Fan & Star" opened a surprise support event for TWICE's Dahyun on the 9th. It is a global fanship project where advertisements to celebrate his birthday are posted in various places.

Dahyun's birthday event will be held simultaneously at 'Fan & Star Korea, China, Japan, English, and Vietnam'. It adds meaning to the fact that domestic and foreign fans can participate together.

Participation in the event is available at the ADs section of Fan & Star's website. It is a way of donating rainbow stars (points that fans can collect on the site) to advertising products they want. Stars can be obtained by doing various activities on the site or completing various missions.

Currently, Dahyun's birthday support includes electronic boards at Seoul Subway Station, Jamsil large digital electronic boards, Hongdae M-Screen, Myeongdong Media Facade, Seoul Bus Advertising, and Japanese electronic boards.
