U-KISS's Dongho revealed that puberty is the reason why he wasn’t given many parts in a song.
On the April 20th broadcast of SBS Strong Heart, Dongho said "My puberty period came just as I'm about to debut as a singer. We were in the middle of recording the song for the first time when suddenly my voice didn’t come out. I got panicked."
Dongho revealed “Because of that, my parts in the song were reduced to 8 syllables.”
Hearing this, Super Junior's Eunhyuk steal the attention by saying "8 syllables are considered a lot." He commented on this "That was a lot. I only received 5 syllables" while Shindong replied “I don’t even have any parts. They only gave me a turned-off microphone!" which created a huge laughter among the guests.
