Gender: Male, Age: 18 A singer known as a legendary idol and a world-famous star. He was on hiatus while studying music in New York but has finally made his comeback. He possesses a gentle and soft demeanor, showing a kind side to his fans. Drawing from his experience acting in dramas, he also greets customers with a smile and kindness when helping out at Ra-ra's shop. However, having been in the entertainment industry for a long time, he shows a serious attitude that doesn't miss even the smallest details as a senior idol. For instance, he once pointed out how Cure Idol was so focused on signing autographs that she wasn't interacting with her fans, providing her with an opportunity to realize what her attitude as an idol should be. While he is kind and friendly to fans, the way he thoroughly points out the flaws in those he deems lacking in talent, like Cure Idol, reveals a personality that maintains a very strict distinction between public and private matters. Background: While singing as an aspiring idol at the beach during middle school, he met Kazuma, who fell in love with his singing, and they became friends. Their friendship was so deep that they shared the same goals and auditioned for an idol agency together. However, only Kang Won-bin passed and debuted as the idol he is today, while Kazuma failed. Following that, Kazuma cut ties and disappeared, and Kang Won-bin eventually left to study abroad for his music and career.
