B2ST's Dongwoon appeared on the October 22 installment of MBC's 'Radio Star' and talked about fellow member Yoseob as well as MC Kyuhyun.

First, Kim Gu Ra complimented Dongwoon on his looks, saying, "You're too good-looking to be an idol.  An idol is not popular if he is too good looking.  Who is the most popular in B2ST?"

The MCs predicted that either Kikwang or Doojoon would be in first, but Dongwoon said it was actually Yoseob, causing them to bombard him with questions.

Kim Gu Ra asked him, "When you first saw Yoseob, didn't you think for sure, 'He's probably going to sing'?  Didn't you think, 'I will make up for the aspects that you lack'?" Yoon Jong Shin added, "Didn't you think, 'If it's Yoseob's standard, I could come out on top'?"

Dongwoon said, "Anyone can think those things.  Because I'm tall and my face is all right, I thought it'd be okay," making everyone laugh.

In addition, he was asked if he had ever gone drinking with MC Kyuhyun.  Dongwoon replied, "I was with the members and Kyuhyun was with his close friends.  Doojoon and I went over to greet him," which caused Kim Gu Ra to cut in with, "Doesn't Doojoon not have to go over there?  He's more popular," making Kyuhyun cutely burst out in disbelief and Dongwoon erupt into laughter.  The other MCs played along with Kim Gu Ra's statement to continue teasing Kyuhyun.

Then, Dongwoon continued, "At the drinking table, Kyuhyun was sitting in the center and we were sitting on either side.  He must've been a bit drunk.  He grabbed our hands and asked us what our blood types were, so we said, 'We're blood type A,' after which he said, 'I'm also blood type A.  Now we're brothers.'  I was really touched and while he gave us his number, he said, 'I'm not being like this because I'm drunk, so make sure you contact me.  I'm not the type who sobers up and doesn't contact you.'  He did contact us afterwards, but following just that one time, there was no exchange."

Kyuhyun responded, saying he has no idea why he asked for their blood types.
