Fans are reacting to Seventeen's Mingyu hitting the like button and then unliking an Instagram post by BLACKPINK's Jennie. 

A few days ago, Jennie posted a photo promoting her upcoming solo album 'Ruby,' set to release in March. One fan discovered that Mingyu had "liked" the post when it was first created. While some fans viewed this as a supportive gesture, some fans criticized Mingyu.

The netizens who supported Mingyu pointed out that he was already good friends with BLACKPINK's Lisa, hence he was just showing support for her fellow groupmate Jennie. The ones who criticized Mingyu suggested that Mingyu should use a private account for such interactions, accusing him of "snooping" on female idols' activities.

Korean netizens debated:

"Isn't Mingyu close to Lisa in the first place? I guess he must be close to the BLACKPINK members."

"A few years ago, NCT’s Doyoung also made a mistake of liking Jennie’s post, so what?"

"If you're going to lurk on female idols' Instagram, at least do it privately..."

"Oh, it could just be as industry colleagues, what’s the big deal with that… You guys probably want to deny it, but famous people all check each other's information."

"Sigh, I just wish he could look at Instagram privately. Mingyu, you know that if you accidentally like something or follow someone, people will talk about it. You’re being way too careless. Mingyu has made mistakes multiple times with following and liking... Please just look at it privately."

"Mingyu even follows some weird idol video accounts and makes so many mistakes."

When male idols make mistakes, female idols get blamed, it's like a rule. Don’t male idols take care of their fingers properly, seriously?"

"Are you mentally weak? Does a like make you go crazy? Aren’t you tired of being so shady?"

"So what are these people trying to even say?"

"He probably just accidentally pressed it while scrolling on his feed. Haven’t you done that too? I still make mistakes."

"So what if he liked something? Is it really that big of a deal?"

"Jennie and Woozi are close, Lisa and Mingyu are close, so they could have pressed it."

"He could be close friends with Jennie, right? He's also close to Lisa, and Jennie even came to his concert."

"This was five days ago, what's the point of bringing this up now?"
