'Entertainment Relay' met up with SISTAR on the set of their advertisement where they were asked, "You've done many advertisements but is there still an advertisement that you want to do?" Hyorin shared, "I want the four of us to do one without any makeup and bare-faced", to which the reporter joked, "You should think about the people watching." Hyorin shared her confidence in her group's bare-face beauty, "SISTAR's skin is good."

When asked if it's difficult or fun to film her drama, 'Love Through Song', which has been surpassing the 30% viewer rating mark in viewer ratings during the weekend, Dasom shared, "I don't have time to sleep a lot. There are times when I sleep for two hours. Please save me." Hyorin, who knows what she's going through with her own solo debut, comforted her, "Unni will save you."

Dasom continued, "I am looking at the precious comments of the viewers well." When asked, "Are there negative comments?", Dasom replied without hesitation, "There are a lot. Please watch it prettily. Negative comments! I will work really hard!"

Hyorin also shared her group's Christmas plans, "Since we have to all gather together and show a new image on stage. We will probably definitely have a schedule then. It would be a miracle if we don't." Dasom added, "During the three years since our debut, we haven't went out to play [on Christmas] once." Soyu then shared her gratitude for her 'sistar's, "But I think it's good to do work with the four of us together. I am really happy to spend Christmas with the four of us members." But when asked if she loves the members, Soyu brought laughs by responding after a pause, "Yes."
