During one part of the show, he revealed, "During my break from activities, I succeeded in quitting smoking." When asked what prompted him to make the decision, Heechul said, "I've been thinking I should quit and around that time, a person I had my eye on said that it'd be good for me to stop smoking."

But what really convinced him to quit was the status of his gums. He warned others who smoke as he said, "Once your gums start changing colors, they don't go back to how they used to be. Normally they would be pink, but after you smoke a long time, they start turning purple. It's not attractive. Sometimes you'll even see girls who look so pretty on the outside and then they'll smile and you'll see purple gums. I started noticing that my gums started looking kind of purple. It's not attractive at all, so I recommend quitting."  

In addition, while he was answering questions sent in by fans, he answered "no" to the comment that read "Kim Heechul is completely natural, he's never had any type of procedure or surgery". He explained, "My nose got broken before so it was crooked. While I was working as a public service officer, I got surgery to correct it. But the bridge of my nose became a little flatter than before. The doctor told me that because that part was where it broke, if I wanted to return my nose bridge to its original height, I'd have to get fillers or silicone injected. But I was scared about doing that, so I didn't."
