On March 8 episode of SBS' television show 'My Little Old Boy', Yook Sungjae featured as a guest.
During the talk, Yook Sungjae reminisced the past when he acted in 'Guardian: the Lonely and Great God' with Gong Yoo and Lee Dong Wook.
He continued, "You know how fathers typically seem a little less attentive than mothers even when they are as attentive as them, right? That was Gong Yoo."
He added, "Gong Yoo would be like, 'Come and eat, Sungjae.' He would always care for me like that."
He went on, "I also remember him giving me this advice, 'You are doing great right now, but I personally think it would be better for you to lower your eyes about 45 degrees there.'"
