This event is a support-type event where fans from home and abroad can participate together. Success depends on the number of stars (points that can be collected on the site) that fans donate to the project. The more stars gather the more celebratory advertisements appear in various places.

If 50,000 stars are gathered, a congratulatory video will be shown on the CM Board at Hapjeong Station on Seoul's subway line No. 2. If the number of stars reaches 100,000, congratulatory images will also be exposed to SM Board (wall) at Gangnam Station, Subway Line No. 2.

When the number of stars reaches 200,000, celebratory videos will also be shown on the electronic boards of the waiting rooms at 43 stations on Subway Line 2. In addition, various products such as the Apgujeong CGV screen, the Hongdae Station Multivision, and foreign-only bus advertisements are available.

Lua's birthday project runs through Tuesday and can participate in the "Star Market" section on the "Fan & Star" website.

Meanwhile, "Fan & Star" held birthday support for member Lucy on Aug. 6. With the participation of many fans, the number of stars surpassed 50,000. Lucy's congratulatory video was shown on the CM board at Hapjeong Station for a week from the 27th of the same month to Sept. 2nd, drawing attention.
