INFINITE's Sungjong revealed his hardships due to sleep deprivation.
On December 10, INFINITE held a press conference for their reality show program "INFINITE's Showtime" at the CGV theaters in Seoul.
One reporter asked, "What's the hardest part about filming for 'Showtime'?" and Sungjong answered, "Not getting enough sleep."
Sungjong continued, "We're still on our world tour and filming a reality program on top of that really gives us no time to sleep, making all of us a little bit more sensitive. There is really nothing more than that."
"Even if we don't get sleep, we're just happy that we're able to have a world tour and to film for 'Showtime'," he added.
