Yeah, Girl's Day's Yura drew those pictures (I'll believe it for now at least.)
And why the fuck is she an idol?
Yes, we know she's hot and an idol so she'll get more fame as an idol than as an artist. But seriously, what the hell? If I could draw that well I wouldn't be wasting my time, slaving 18-21 hours a day every day in order to be an idol. Idols don't make shit unless you're from a big company. I bet most of Yura's paycheck comes from the horny 50-60 year old guys in show business making Yura suck their wrinkly dicks and tickling her face with their gray pubes.
Yura needs to drop out of Girl's Day and become an artist. Will be be rich and famous for her art? Probably not. But she could improve her artistic skills and make much more money while working a lot less if she became an artist.
