"Son Na Eun, happy birthday."

The place where fans and stars are together, "Fan N Star," opened the birthday project for the group Apink Son Na Eun on Jan. 17. It is a big advertising event to celebrate his birthday on Feb. 10.

The project will be carried out simultaneously at "Fan N Star" Korean, Chinese, Japanese, English, and Vietnamese services. Especially, fans cheering for Son Na Eun are known to have applied for the event.

The way to participate in the project is simple. It is a way to donate the star that fans eagerly collected (a point that can be collected on the site) to the advertising products they want. The number of donations is unlimited and anyone who is a fan can participate.

Currently, the Son Na Eun birthday project has 10,890 stars and is set to achieve the CM Board ad at Hapjeong Station in Mapo-gu, Seoul.

In addition, 43 subway stations on subway line No. 2 are equipped with electronic signboards, SM boards (walls), Hongdae Station Multivision, Travel Bus, CGV Moving Wide on Daehangno, and Myeong-dong Media Facade.

With the Son Na Eun birthday project running through Jan. 31, attention is being paid to whether it will be successful for the rest of the year.
