On the December 6 airing of MBC's 'Radio Star', Hoya joined as the guest. One of the questions given to the idol star regarded his vow to premarital chastity. Regarding this, Hoya revealed, "I've never announced or officially vowed to it. I was on a radio once and asked, 'I heard you like writing provocative lyrics. Is this coming from your experience? Do you have a lot of experience?' I answered no, and explained it's all from my imagination. We were joking back and forth about it and it built up, and the articles ended up going out like that."

MC Kim Gu Ra then asked, "Oh, so you have no intentions (for premarital chastity) at all?" Hoya expressed concerns about relationships being taken too lightly and replied, "Well, there is no line nowadays. Rather than premarital chastity, I'm more towards a post-marital relationship."

Yoon Jong Shin commented, "That's basically the same thing... After wedding relationship."
