TS Entertainment labelmates Song Ji Eun and Bang Yong Guk shared a photo they took backstage together. The SECRET member wrote through her Twitter,�"Hello, Palja (smile line) Yong Guk? I gave Yong Guk a nickname." The two are currently promoting for Ji Eun's solo track, "Going Crazy" - a dark duet detailing the terrifying nature of obsession. The photo amused netizens because of their playful images, which is vastly different from the ones they show on stage. Fans commented, "They look different from when they're singing," "They must be so close since they're the same age," and "Such cute face expressions!" After taking a brief break because of a cold, Ji Eun will be returning to the stage through KBS's "Music Bank" on March 25th. Source: Asia Economy via Naver Tip: meeshell
