Is Yoobin upset over her weight?

Wonder Girls member Yoobin apparently posted a disturbing message on her cyworld recently with an entry titled: "Please, no more..." In the entry she wrote: "I Know, so please stop it... I feel it, so please stop now..." Sookyeong took a screenshot of the entry shown below but the entry was deleted shortly after it was posted. Wonderkid did some research and stated that her body was hotly debated recently on the Daum message boards, saying that she has become fat. Also, if you do a search for Yoobin on Daum (one of Korea's most popular search engines) the related searches show up for "Yoobin's body, Yoobin fat, Yoobin pictures when she was skinny." If you look at the pictures, you can see that Yoobin has gained some weight. But she isn't fat by any means. I prefer Yoobin now than before, it's good for a girl to have some meat on her bones. She's beautiful just the way she is, now if she turns into the Goodyear Blimp... that's a different story. Poor Girl, Yoobin just needs a hug and I'll definitely give her more than that if she wants...
