When told by the interviewer that a variety show like 'Roommate' would suit him, Ji Chang Wook shared, "I got asked by Shin Sung Woo hyungnim and [Park] Min Woo to come on 'Roommate' as a friend, but I really respectfully declined [the invitation] because I have no confidence to go on it."

When asked how he got close with the two roommates, he explained, "I did 'Jack the Ripper' with Sung Woo hyung and I became close with Min Woo by drinking [together] and ended up being soccer buddies. I joined that team because of Min Woo but since Min Woo is busy these days, I don't see him often [laughs]."

When asked about the past controversy surrounding Park Min Woo due to his incidents on the reality show including his driving while being drowsy, the actor recalled how he worried for Park Min Woo. He shared, "I wasn't aware of it because I don't watch TV often, but it was all over the internet one day. [Min Woo] has a big sense of responsibility so he hates being an inconvenience to others, has to do things himself, and [feels the need to] take care of others. Compared to his age, he is a more grown-up style. He has a lot of thoughts and is sensitive. He is sensitive, but is deep, mature for his age, and a very kind dongseng. I felt bad for him. That is why I called him, asking if he was okay. But he seems to be doing well."
