Actress Oh Nara opened up about her relationship of 20 years. 

The actress from the trending drama 'SKY Castle' frequently mentioned her 20-year relationship with former musical actor and current acting instructor Kim Do Hoon. 

In an interview on February 7, Oh Nara once again talked about her relationship. She commented, "I didn't think it was this amazing thing (to be dating this long). 20 years just somehow passed."

She continued, "It's not that I'm against marriage. I just couldn't get married because I was too busy. We have kept delaying it and ended up coming all the way here." Oh Nara added, "In a way, I feel like we need to do it one day but in another way, I wonder what's the point when 20 years have already passed." 

Oh Nara also stated Ki Do Hoon is already a family to her and marriage does not have much meaning in their relationship.
