Mr.Mr is a South Korean boy group who debuted in 2012 under the management of TH E&M with their first digital single 'Who's That Girl' on October 4, 2012. The group consists of Jin, Doyeon, Changjae, Tey, Sanghyun and Jaemin.
Member Hon left the band after the controversy involving a transgender woman in 2014.
On March 4 2015, the agency released a statement regarding Ryu leaving the group in a fan cafe without stating the reason for his leave. A few days later, Ryu himself saw the statement and was deeply shocked by it. He has taken to Twitter to address certain complaints including his unfair treatment, physical and verbal abuse which he had received while still being in the group. Since then, both parties have been exchanging responses and Ryu has officially filed a lawsuit against his agency's CEO. Following his leave, MR.MR will continue on as a four-member group. MR.MR has announced their comeback plans for April with a new member set to join them.
