Idol fandom's play space "Fan & Star" launched a birthday project for the group TOMORROW X TOGETHER HUENING KAI on Wednesday. It's a surprise advertising project for him, who will celebrate his birthday on April 14.

HUENING KAI's birthday event is open to both domestic and foreign fans. In particular, congratulatory messages written by fans will be featured in some commercials through a lottery, adding significance to the event.

Participation in the event can be made at the Star Market section of the fan and star website. If fans donate their hard-earned stars directly to HUENING KAI's birthday market, the application will be completed. The number of applications is unlimited.

HUENING KAI, which is loved by many for its sculptural appearance and youngest-ever fresh charm, is drawing attention to whether the project will succeed to celebrate his first birthday since his debut.

Meanwhile, TOMORROW X TOGETHER, which includes HUENING KAI, took its first step into the music scene by releasing its debut album "Dream Chapter: STAR" on March 4. Before its debut, it was called the younger brother group of BTS, the same agency, and drew attention.
