JYP's official announcement on Wonder Girls, Sun-mi and Lim.
On the 28th, JYP made an official announcement regarding Wonder Girls through their fan homepage.
Firstly, JYP asked the public to excuse the agency's late reply to the incident as the agency avoids talking to reduce miscommunication.
Most importantly, he explained that Lim has to fill the absence made by Sun-mi, as her departure decision has been rather sudden and affected other contracts. The clients were promised a 5 girl band, making Lim's presence an absolute necessity. Secondly, the 4 girls have agreed to introduce a new member as things can be tough with an absence. All the girls have agreed on this matter.
Furthermore, if Sun-mi wanted to return to Wonder Girls, it would not be a problem as the band could expand to 6 girls.
