”BTOB” Yook Sungjae, after meeting ZICO (Block B) for the first time in a while, has the misunderstanding been cleared up? ”You're not avoiding me, are you?” = ”Artist”

Actor Yook Sungjae, a member of BTOB, and ZICO of Block B met and talked.
In the episode of "SEASONS - ZICO's Artists," the appearance of Yook Sungjae was depicted. On that day's broadcast, ZICO said, "I'd like to introduce Yook Sungjae, who is hexagonal and perfect in every way."
On stage, Yook Sungjae showed off his singing ability by singing "Fate." Yook Sungjae then explained why he chose "Fate," saying, "I like J-POP, so I wanted to sing that kind of song."
Zico said, "It's been almost seven or eight years since we last met. There are many stories behind this, but we never had a chance to face each other."
Yook Sungjae then laughed and said, "I thought you were avoiding me." Zico asked, "Did you have a story with me?" Yook Sungjae replied, "We're BTOB
"When 'Block' was still in the dark, Zico sang for us and we even recorded it," he said, "We tried to release a ballad, but it didn't work out, so we decided to do it next time, but then 'Block'
It was on the album "B" and I think that's why he avoided us."
ZICO hastily replied, "If there wasn't a singer, I wanted to release it quickly, so I chose 'Block B'," drawing laughter.
