On February 25, pediatric and adolescent psychiatrist Kim Bung Nyeon, a leading authority from Seoul National University, appeared on KBS 2TV’s Problem Child in House to assess the psychological and behavioral traits of the cast members. The segment captured particular attention for its insight into singer Kim Jong Kook’s personal transformation following marriage.
Joo Woo Jae revealed Kim Jong Kook’s long-standing, unusual organizing habits, joking that his space looked like “a pile of trash” despite claims of being organized. However, after his marriage, Joo Woo Jae noted, Kim Jong Kook began showing a markedly different side, as his wife took over organizing responsibilities at home.
Professor Kim Bung Nyeon explained that people with such habits typically resist anyone touching their personal space. The fact that Kim Jong Kook accepted this change, the psychiatrist noted, demonstrates his deep love and respect for his wife.
The revelation left cast members astonished, as Kim Jong Kook reportedly gave up lifestyle habits he had maintained for over 22 years. His willingness to adapt to his spouse earned him admiration and the label of a “hopeless romantic.” The segment highlighted how personal relationships can inspire meaningful behavioral changes, revealing a softer, more accommodating side of the singer that had never been publicly observed before his marriage.
