THE BOYZ have taken heat for multiple issues.
Recently, THE BOYZ‘s have been involved in several rumors and allegations.

Member Juyeon seems to be the one at the center, as following his dating rumors, more “bad” behavior from the members was exposed.
Members Hyunjae, Sunwoo, Eric, and Sangyeon have all been implicated, with several being accused of smoking and others allegedly caught drinking with younger women.

As the group faces criticism from some fans, Sunwoo has acknowledged what is happening.

On June 11, on the fan chatting platform Fromm, Sunwoo shared messages with fans, telling them to disregard the rumors. He also offered a code for fans to join him in playing a game.

He followed up with another response, seeming to apologize more formally after realizing what was going on.

The Bs, I spoke too lightly and played games without being aware of the situation, even though I didn’t fully understand what The Bs were going through… Whatever the reason, I think The Bs must be even more upset. I’m sorry, truly sorry…
— Sunwoo
The reactions were increasingly negative, with his previous scandal being brought up.
Earlier this year, Sunwoo was involved in a bad attitude scandal that grew to involve former Afterschool‘s Nana, who “called out” his behavior. The idol allegedly yelled at a security guard to pick up his airpods, leading Nana to criticize him on more than one occasion.

At this point, I’m reminded of Queen Nana. As expected…

Wait, looking back, Nana-nim actually took the hit and gave advice to Sunwoo — who seemed like he’d been shot in the head — to come to his senses, all for the sake of the pure The Bs who would love THE BOYZ no matter what. So why did she get hate for that?
