Girls' Generation's Yoona thinks that to look beautiful, you must feel beautiful.

On the November 30 broadcast of the segment "Entertainment Relay", Yoona went to Lotte World on a guerilla date, and she answered a few questions for her fans. One of the questions was, "Among the three SM beauties Lee Yeon Hee, Go Ara and Yoona, who do you think is the prettiest?"

Because they were on a ride, she apologized for screaming and took a while to answer before she said, "Yoona!"

The reporter followed up with the question, "You were picked as the number one female celebrity that makes people think of their first love in a poll. You were also picked as the number one idol visual by plastic surgeons. Which poll results do you like better?"

She admitted that she liked the idol ranking more and said, "There are people who say that when they see me on TV, I'm just in the middle of their ranking, but when they see me in person, I move to a higher ranking."

Yoona also talked about her struggles in becoming an actress. She shared, "Before my first drama, I tried out for hundreds of auditions for commercials, dramas, movies, music videos... Having confidence is key. Even if you think you did badly, if you have the confidence, it will become a good learning experience."

On dating, she admitted that there are things she wants to experience. She said, "Normal dates that everyone are used to. Watching movies, eating, going to cafes and taking me home..."

Catch Yoona on "Prime Minister and I" which will premiere on December 9.
