In the recent episodes, Hearts2Hearts performed their track “FOCUS.”
Ahead of their performance, Hearts2Hearts did a comeback interview with the MCs.
During the episode, Hearts2Hearts was doing their challenge with BOYNEXTDOOR’s Leehan.
Yet, when they were dancing, Jaehyun could be heard chanting his real name, “Kim Donghyun,” to the beat of the song, and it came under major scrutiny from fans when the video was shared on social media.

Netizens hit back at the idol’s actions, saying they were rude and inconsiderate, and that if it were a female idol, they would be getting criticism from the fandom.
- Who’s that male idol holding the mic and saying “Kim Donghyun”? Tell me.
- Why is he acting like that? Is it some kind of mission?
- He’s been consistently unlikeable…
- BOYNEXTDOOR, is it you again
- They’re doing an interview to promote the new song, and if he behaves like that during that short moment, of course people are going to talk LOL Not exactly a huge scandal, but it just feels very Block B-like. [BOYNEXTDOOR’s company founder is Block B’s Zico]
- If a female idol or another male idol did that, people would be throwing fits. What a hypocritical fandom lol.
- Did he lose his sense of decency or what?
You can watch the whole interview.
