When Sung Yuri commented, "We heard that you're close to Hong Jong Hyun, Sung Joon, and Kim Woo Bin," Lee Soo Hyuk replied, "When I'm out with Kim Young Kwang and Hong Jong Hyun, my head is spinning. They get hyper like children."
The actor also exposed that he became close with Kim Woo Bin, Sung Joon, Hong Jong Hyun, and Kim Young Kwang after filming drama special 'White Christmas' together. He further stated, "Sung Joon is similar to me because he likes looking at photos and because he is a bit rebellious. Kim Woo Bin acts so upright and honest even towards us that we feel like bad people when we're with him," causing laughter.
Lee Soo Hyuk also explained, "I think the reason we're able to maintain our friendship is because we are all active together and because we have similar dreams. Scripts are distributed equally to us. Sometimes they go to Young Kwang first and sometimes they come to us, but these days I think I'm better [at receiving more scripts]."
