'CeCi' magazine editor commented, "At first they were a bit awkward, but once the cameras started shooting, they were both very professional and posed skillfully in front of the camera. We only released one sketch cut from the filming, but it went viral in a blink of an eye through SNS so we were able to experience their popularity as well. The actual pictorial has a lot more cuts, so please anticipate [the release]."�
