On the March 30 airing of 'Happy Together 3', the guests were asked about the nicknames they had in school. Kim Se Jung answered, "I was called the Red Hare (a horse owned by the warlord Lü Bu). I enjoyed showing off my strength and racing boys so I got that nickname."
Hani added, "I also had a nickname relevant to a horse. I was called centaur because my muscles were developed."
