f(x)'s Krystal has been put up on the chopping block once again for her rude attitude, only this time it was on SBS's "Kiss & Cry". June 5th's episode revealed the stars' preparation process as they geared up for their first performance. Immediately, viewers noticed an air of tension between Krystal and her trainer, Lee Dong Hoon. Like any trainer would, Lee attempted to teach Krystal from the basics, step by step. However, Krystal proved to be a bit of a difficult student, "He only teaches me the basics, and basics are no fun." With a sigh, Lee remarked, "It was difficult to train her because she refused to learn the basics.�She would just stand there, and even when I told her to skate, she wouldn't." Some viewers felt that Krystal's poor attitude escalated when she bluntly stated, "He's a poor instructor because he's only used to singles.�It's really frustrating." Lee is also seven years her senior, but Krystal didn't hesitate to glare at him whenever their opinions clashed. Netizens expressed, "Is she immature or what? She really doesn't know how to manage her image", and "She received so much hate for her rude attitude last time and she's doing it again." Source + Photos: TV Report via Naver
