On the KBS 2TV show 'Men of Housework' that aired on the 22nd, N.Flying's drummer Kim Jaehyun appeared as a special guest and shared stories about his sister Kim Jaekyung from Rainbow's wedding. Kim Jaehyun humorously revealed the chemistry between him and his sister, joking that if she were born in ancient times, she would have been a legendary warrior like Lü Bu or Guan Yu, referencing her strong personality. Regarding his sister's husband, whom she married in 2024, Kim Jaehyun described him as 'a sponge-like person who absorbs all of his sister's personality.' He also shared an anecdote about being the MC at Kim Jaekyung's wedding, revealing that she suddenly handed him a script on the wedding day and told him to memorize it.
