Simon D says he tried out CNBLUE Yonghwa's banana diet and utterly failed.

On the 17th, Simon D tweeted, "I wanted to follow Yonghwa and try out his banana diet from 2 or so years ago, so I just drank water and ate bananas. But it was too delicious, so I ate 6-7 bananas at a time and gained more weight. I was trying to diet."

He added, "This is from 2 years ago too. My friend said he'd send me packed lunches for a diet, and I thought it wouldn't taste good at all. But it was so good that I ate a week's worth in 3 days and gained more weight."

Fans commented, "I'm the same way," "The banana diet is hard to do," and "Simon D is so cute!"

Who else can relate to his diet failure? Does he look chubbier than usual in your opinion?
