Park Gyu-ri, a member of K-pop group KARA, was recently questioned by prosecutors as a witness over her ex-boyfriend s alleged business fraud. Park was a curator of a gallery that belonged to a local art-sharing platform operator, Pica Project, where her ex-boyfriend, Song Ja-ho, was the CEO. The company issues a crypto token named PicaArtMoney, which it sold primarily to individual investors for use in artwork-related transactions.
