Sung Si-kyung getting flak for asking Sullyoon a completely random question

My immediate reaction was, “Can women not grill meat without a man?” Even setting aside that she's an idol, as a woman it's offensive because that's a sexist, stereotypical remark.

“Someone who'll do 00 for you~ Guess you must have a boyfriend.” That's such a f*cking lame assumption to make.

What does grilling meat on a camping trip have to do with having a boyfriend? How did the conversation even jump there?
