A member of SM Entertainment's choreography team and former�Black Beat member,�Sim Jaewon, left an indirect message for�JYJ through�his personal Twitter. On January 7th, he wrote, "I can't just hold back any longer.. Hey, little brother, that's not right at all.. Who do you think you are pointing fingers at?� Don't act like you're so upset.� Who's the real one that's hurt in here...?� So ungrateful, how could you do this?"
