On the February 14 airing of '1 vs 100', Yoseob revealed that he nags his fans. He explained, "Idols are role models for teenagers and I believe that we have the ability to shift directions for many people. So I think it's idols' duties to say that wrong is wrong."
He continued, "When my fans leave malicious comments on other celebrities, I tell them to stop. When they come to our dorms and doodle on the walls, I tell them not to do that in public places but just draw on our car instead."
