When questioned whether he was a girl group otaku, Kim Ji Hoon replied, "There is a misunderstanding. I've been watching music programs since the 'Top 10 Songs' days. Sometimes when I'm bored, I re-watch the programs. I just have an interest [in them]. Rather than an otaku, I'd consider myself more as somewhere between a music critic and your average person. 

The actor also said, "I'm a fan of TWICE's Tzuyu, and she's hot right now (as in rising star) but once people are used to her, I think Chaeyoung may have the potential [to be the next big thing]. She hasn't reached her full potential but I think she could do okay."

Kim Ji Hoon then revealed how shocked he was at Chaeyoung's age. He explained, "What surprised me was that Chaeyoung had just entered high school. So I'm careful with my words. I don't want to seem like this weird ahjusshi." I think the damage is already done Kim Ji Hoon...
