During the press conference for Lee Jong Suk's drama, 'W', on July 18, he was asked about Kim Woo Bin and his current drama 'Uncontrollably Fond.'
Lee Jong Suk said, "Kim Woo Bin asked me to make a cameo in 'Uncontrollably Fond' before I confirmed my appearance in 'W', so I almost did appear. However, I was unable to make a cameo in 'Uncontrollably Fond' in the end because it airs the same time as 'W'. We have a symbiotic relationship to the point that we consider ourselves spiritual companions. We told each other, 'Whoever does well should buy a meal,' and support each other.
"Because of my busy schedule, I've been unable to watch 'Uncontrollably Fond' so far, but seeing the still cuts or previews, it seems that Kim Woo Bin worked out a lot. I wondered about taking it off in my drama this time, too, but [after seeing his body] I decided not to."
