Next, Soyu said, "The most memorable thing for me is SISTAR's last broadcast. I'm sorry to the fans but we really had a good separation. It might sound funny but we went our separate ways with a smile and with encouragement for one another."

Hani commented, "I think relationships like that are hard (to have). It's sad but also amazing. I think you guys are the wannabe of many girl groups."

Soyu replied, "I often heard it's brave to leave when people give you an applause."
