It was revealed last month that Jaekyung was the art director for Rainbow BLAXX's debut, designing things from the main prop on the stage to the girls' logos. She appeared on KBS 2TV's 'Full House' on February 7 and showed more of her art skills.

She said, "When I wanted to relieve stress and take control of my feelings, I did calligraphy. As I was the art director for Rainbow BLAXX, I put my calligraphy into the album." She showed off some of her beautiful and neat calligraphy that looked so good they practically looked printed.

Jaekyung also shared a secret she put into Rainbow's logo. She continued, "I even made the logo for Rainbow this time. If you hold the logo up this way, it becomes a drawing of a female figure." Indeed, if you look at the picture above, she propped up her writing for 'BLAXX', revealing a drawing of a woman's body!
