BOYNEXTDOOR‘s Leehan is facing backlash from Korean netizens after a TikTok collaboration with senior boy group EPEX left fans feeling less than impressed.
The video, posted on EPEX’s official TikTok account, features Leehan joining an EPEX member to perform the group’s choreography as part of a challenge. While the concept itself seemed harmless enough, it’s Leehan’s noticeably low energy throughout the clip that sparked the controversy.
Compared to the EPEX member beside him, Leehan appears disengaged, and netizens were quick to call it out.

Korean fans didn’t hold back in the comments, with many pointing to the video as a clear sign of disrespect toward his seniors.
This is embarrassing even for me.

No, seriously, this is just freaking hilarious. The fact that both of them watched this during the review process and went, ‘Yep, looks good!’ before uploading it makes it even funnier.

If you’re going to dance that half-heartedly, then just don’t do challenge videos in the first place. Nobody’s forcing you. ^^

Why the hell does Leehan never fix his attitude? He’s been called out and criticized for it so many times, and he still doesn’t change. Seriously, what the f*ck is wrong with him?
