Netizens noticed that AOA's Seolhyun commented on Choi Tae Joon's Instagram photo. Choi Tae Joon's photo had a caption that read, "Stop being cute," and Seolhyun's reply was, "Me? Or the cat?" 

Some people claim that Seolhyun was being flirty, and some are defending her, saying that the two are friends. 

Here are some of the netizen comments: 

"Don't hurt our Bomi [his 'WGM' wife]"

"...I wish they were a bit more cautious...Choi Tae Joon is filming 'We Got Married'... 'WGM' is scripted, but they should still be considerate. Seolhyun is funny too. Why does she have to leave such a loaded comment in public?"

"Why did she suddenly delete [the comment]?" as Seolhyun has since deleted her comment.
