afaik there are two big "scandals" attached to yoseob, the first being that he made a public apology on behalf of his fans and made them apologize to the apartment owners after they scribbled beast graffiti on it in order to get their attention

the second thing was how he was rumoured to be in wgm with jaekyung, and fans started sending her a ton of hate messages and yoseob put some long letter on his cyworld telling his fans to back off and that he should get some hate too bc they were both casted for it, and he told them to direct the hate for jaekyung onto him because he's a man and he can take it

and some na anons got really mad that he was perpetuating gender roles by saying that jaekyung couldn't take the hate and he could, and by acting like she needed his protection
