On the February 21 airing of KBS Cool FM's 'Jung Jae Hyung and Moon Hee Jun's Joyful Life', Shoo joined as the special DJ. 

H.O.T's Moon Hee Jun made a comment about his former labelmate Shoo and said, "She was a quiet girl. She was well known in the agency for it. Lee Soo Man seonsangnim was concerned because she was so quiet. On the other hand, he was worried about Bada because she was so talkative. He said it would be nice if we could mix their personalities."

Hearing this, Shoo recalled her past S.E.S days in SM and said, "There was a rule where we were not allowed to even say 'hi' to H.O.T sunbaenims. If we greet them then things went wild. We were most afraid of getting criticized by H.O.T's fans."

Moon Hee Jun then said, "Our fans liked S.E.S because we were from the same agency. Later on, it felt like we were one."
