During her interview, the actress surprised by revealing that she has a boyfriend she's been dating for 20 years! The two met during their early twenties, Oh Nara shared. "Even now, if we decided to, we could get married. But I believe that marriage does not hold much meaning in our relationship. We are already nothing short of family. Rather than worrying about marriage, it is more important for us to wonder what dreams we dream, and how we can live on together," The actress stated. 

In 'My Mister', Oh Nara appeared as the owner of 'Junghee's', a small restaurant that served as a resting place for many of the characters.
