Actress Yoo In Na may be in a romantic relationship with actor Ji Hyun Woo, but she reveals, that there is someone else she treats as her soul mate.

In a recent interview, Yoo In Na talked about her best friend IU, and she shared, "IU and I are very comfortable with each other. It's the kind of friendship that makes you think you'll be friends with each other for the rest of your lives. We're lucky because not a lot of people in the entertainment industry would meet a friend like this."

She added, "We started talking about things that friends wouldn't usually like to talk about, and we developed a real friendship in spite of the large age gap. I honestly think that IU and I are soul sisters."

When asked how they became friends, she answered, "I have a lot of abstract thoughts, and it's the same for IU. Since I met her years ago in the variety program "Heroes", we realized that we have a lot of things in common, and that we have the same kind of souls."

"Even though I went through hard times before being an actress, I was able to meet IU through it, and it was worth the fight," the actress concluded.

Yoo In Na recently finished her drama "Man From The Stars".
