Fan & Star, where fans and stars become one, conducted a birthday project for the group ITZY Chae Ryung on Friday. The event is a large advertising event to celebrate Chae Ryung's birthday on Jun 5.

Success will be determined by the achievement rate of stars (points that can be gathered on the site) based on fan participation. In addition, it is expected that the birthday ads will include congratulatory messages written by fans themselves.

50% (starved) is equivalent to 2% SM (wall) compared to CM (board) compared to CM (square column).

If the number of stars rises to 200 percent, congratulatory videos will also be shown on the electronic display board of the waiting room at 43 stations on Subway Line 2. When 400% of stars are reached, images are exposed up to Apgujeong CGV screen. In addition, a variety of gifts are waiting for fans, including a multivision at Hongdae Station and a advertisement for a travel bus.

Chae Ryung's birthday support runs through Wednesday and can participate in the "Star Market" section on the "Fan & Star" website.

Meanwhile, ITZY, which includes Chae Ryung, made its official debut in February by releasing its digital single album "IT'z Different" and title track "DalaDala."
