On the January 18 airing of JTBC2's 'Soyu x Hani's Beauty View', the two idol stars had a pajama party. While chatting about various topics, Soyu and Hani talked about the most memorable moments of 2017.

Hani first said, "2017 will really be a memory. I remember having only the good memories with the members and unnies who I love when I look past."

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."
