Actor Yoon Si Yoon described the good memories made while working along with co-star YoonA of Girls' Generation on "Prime Minister and I".

During the recent interview with Sports Seoul, actor Yoon Si Yoon revealed what it was like to work with YoonA, stating, "YoonA is very down-to-earth, good person. She is a good actress who's got her heart in the right place. She is an actress who delivers emotions beautifully. Although it may not be impactful, her stable and sincere acting is her strong point. In the not-too-distant future, I think she will be able to act in a film like 'Classic', which is calm but shares a deeper message. Although she is part of the girl group Girls' Generation, she has an analog-like charm as an actress. But she also shows an explosive energy on stage, and I believe that is the result of much effort."

He also compared Girls' Generation to H.O.T and according to his explanation, "Girls' Generation already made a mark in history. Like H.O.T, aren't they a group that makes a lot of buzz? I hope YoonA enjoys it to the fullest. When YoonA comes on TV, I will make sure to monitor her well and cheer her on!"
