INFINITE's Sunggyu admitted it was awkward being around Tablo, who featured on one of his new songs, again after three years, but also showed his gratitude.  If you recall, Epik High used to be a part of Woollim Entertainment and were mentors for INFINITE in their earlier days.

On the May 14 installment of KBS radio program, 'Kim Sung Joo's Music Plaza,' Sunggyu was asked, "Did you lose Tablo's credit card in the past?"  He replied, "That's right. I don't know how everybody remembers that," and laughed.

Then, he continued, "I saw him for the first time in three years while working on this album. It's like that with guys.  At first, it was a bit awkward, but then it got okay.  I'm really thankful for his participation."
