Lee Hyori, Uhm Jung Hwa, Jessi, and HwaSa met for the first time to form Refund Sisters, a new project girl group. They've talked a lot about responsibilities of groups leader, then Jessi suggested that she can do it but HwaSa calmly said "no", and Hyori and Jung Hwa also looked like they can't see Jessi in this role. During talks, Uhm Jung Hwa said that she doesn't want to be, a leader, and in the end, ladies decided that Lee Hyori will be a group leader.
