On February 7, Yunho guested on SBS' 'I'll Win You Over with My Channel.' While filming, Yunho insisted Kang Ho Dong move back a little because of the big difference in their head sizes.
Kang Ho Dong coolly reacted, "I'm alright. I have no concerns about head sizes. No fear!" Yunho replied, "Oh, really?" But after looking at the monitor, Kang Ho Dong brought laughter as he said, "Hey, but seriously, is this (size difference) real?"
Netizens also laughed and commented, "Lolol Yunho's head is so tiny," "I can't tell if Yunho has a tiny head of Kang Ho Dong has a big head, or if it's both lol," "LOLOL They both are so cute," "The different tho."
