On the April 25 airing of MBC Every1's 'Weekly Idol', the MCs asked VIXX, "Now, isn't it embarrassing when you think about the times you had fights?"

In response, Hongbin shared how childish Leo acted, and said, "Leo hyung said we should use honorifics to one another now since our relationship is only business." 

The MCs burst into laughter. 

Hongbin continued, "It was when we were preparing our album. We fight the most during that time", and revealed Leo used honorifics in the studio, even to the younger members.

Ravi also made fun of how Leo said he'll never see him again. Hongbin added that Leo used honorifics in their group chat, only to the members he fought with. 

Leo denied Hongbin's last statement, and said, "No, no. That's a lie."
