On the May 10th broadcast of KBS 2TV's 'Entertainment Relay', Choo Sung Hoon was humble about Choo Sarang's title as the 'nation's baby', sharing, "They're the cutest at this age. I don't think it's especially Sarang who is cute. She is a baby right now so she's cute but when she grows up, she can become ugly."

Sunny, who is known to be a fan of Choo Sarang, was asked, "Would you want a daughter like Sarang?", to which Sunny replied, "If only I had a guarantee that that will happen."

When asked to choose favorites, "Among Baro and Sunny, who does Sarang play well with more?", Choo Sung Hoon chose Sunny, explaining, "It's the third time we're seeing Sunny and we met Baro for the first time today so I think of course, Sarang likes Sunny."

Sunny shared, "We're doing a good love sharing campaign together so we were able to get together." Choo Sung Hoon also revealed his goal to be a role model for his daughter, "If I [take part in charity campaigns and donate], I hope she follows what I do when she grows up so I am doing donations, etc."
