"Listen to Taeyeon's solo concert."

Idol Fandom's playground "FAN N STAR" kicked off a special event on Dec. 23 for the group's Girls' Generation Taeyeon. This is a cheering ad project for Taeyeon, who will hold her fourth solo concert next month.

This is a support-type event where SONE (the name of the Girls' Generation fan club) from around the world can participate together. The number of stars that fans donate to the project (points they can collect on the site) will determine their success.

When more than 20,000 stars are gathered for the project, congratulatory advertisements will be shown on the CM Board at Hapjeong Station in Mapo-gu, Seoul. If there are more than 45,000 stars, there will be a congratulatory video on the SM board of Gangnam Station.

In addition, there are plenty of other products available, including a waiting room at 43 stations on subway line No. 2, Tokyo Shinjuku, Myeong-dong Media Pasad and advertisement for CGV trailer in Hongdae.

Currently, 8,200 stars are gathered in Taeyeon's solo concert cheering project. With the event running through Jan. 5, we are looking forward to its success for the rest of the year.

Taeyeon will host "TAEYEON CONCERT - THE UNSEEN" at SK Olympic Handball Stadium in Seoul's Olympic Park for three days from Jan. 17-19.
