On July 30, a representative of MBC's Saturday variety series 'Hangout With Yoo' confirmed with media outlets, "Lee Hyori, Uhm Jung Hwa, Jessi, and Hwa Sa plan to hold their first meeting as the 'Refund Squad' on July 31." 

Previously during 'Hangout With Yoo', Lee Hyori a.k.a Rinda G of SSAK3 mentioned that she wanted to participate in a project girl group made up of members including herself, Uhm Jung Hwa, Jessi, and MAMAMOO's Hwa Sa. The staff of 'Hangout With Yoo' then decided to put this plan forth into action, and it seems likely that fans will be able to see this one-of-a-kind project girl group debut some time this year!

Meanwhile, Rinda G is currently promoting as a female member of co-ed project group SSAK3, sweeping domestic music charts with their debut song "Summer Once Again".
