He added, "But if I date, I put my everything into the relationship. If we go out, I take care of everything. I can't stand seeing a girl flustered and not knowing what to do".

But apparently, even the mighty Kim Hyun Joong makes mistakes. He confessed, "Once, I called my girlfriend by my ex's name. I made the mistake and it really surprised the both of us."
